Worksheet 21: The Mean Value Theorem Russell Buehler b.r@berkeley.edu 1. Verify that f (x) = x3 − x2 − 6x + 2 satisfies the hypotheses of Rolle’s theorem for the interval [0‚ 3]‚ then find all c that satisfy the conclusion. www.xkcd.com 2. Let f (x) = tan(x). Show that f (0) = f (π)‚ but there is no number c in (0‚ π) such that f (c) = 0. Is this a counterexample to Rolle’s theorem? Why or why not? 3. Verify that f (x) = x3 − 3x + 2 satisfies the hypotheses of the mean value theorem on

A Sound of Thunder is a great story written by Ray Bradbury‚ however‚ Nethergrave is an even better story written by Gloria Skurzynski. Though both of these stories are science fiction‚ I enjoyed reading Nethergrave more than Sound of Thunder‚ the story has more of a unique feature to it‚ seeing as it is not set in the future and most science fiction stories are set in the future like A Sound of Thunder. Also the imagery in Gloria’s story grabs my attention unlike in Sound of Thunder. Both of these

I also to notes on what a sound wave is and how frequency affects a sound wave.

sound waves Sound is a series of compression waves that moves through air or other materials. These sound waves are created by the vibration of an object‚ like a radio loudspeaker. The waves are detected when they cause a detector to vibrate. Your eardrum vibrates from sound waves to allow you to sense them. Sound has the standard characteristics of any waveform. Sound is a waveform that travels through matter. Although it is commonly in air‚ sound will rapidly travel

Sound and acoustics It is common to think that acoustics is the study of music. Although acoustics does comprise the study of musical instruments‚ it also includes an extensive range of topics‚ including: SONAR systems‚ noise control‚ ultrasounds for medical imaging and other processes‚ electroacoustic communication‚ seismology‚ etc. [1] In general‚ acoustics is the study of mechanical waves including sound‚ vibration‚ infrasound and ultrasound. When talking about the acoustics‚ it is essential

by making their residential structures reinforcements to absorb incoming sound waves. They do this to avoid certain risks concerning health. This was called “Soundproofing”. Soundproofing is the method of reducing sound pressure with respect to a specified sound source and receptor. It may be approached by sound blocking or sound absorption. Both have different purposes‚ either to reduce sound entering or reducing the sound bouncing inside a room. 1 2 B. STATEMENT OF THE PROBLEM

Experiment 7: Velocity of Sound Laboratory Report Hazel Guerrero‚ Kyle Iddoba‚ Matthew Jocson‚ Thea Lagman Department of Biological Sciences College of Science‚ University of Santo Tomas Espanya‚ Manila Philippines Abstract Verification of the relationship between frequency of sound and its wavelength and the determination of the velocity and the speed of sound in different mediums was the main focus of this experiment. The speed of sound and its velocity was determined using the resonance

Expository Writing 1213 Conference draft Mauricio Cuevas Due Wednesday‚ September 05‚ 2012 The sound of silence “A horrid stillness first invades the ear‚ and in that silence we the tempest fear”(Dryden‚ 7). Silence inevitably starts with a sound‚ which either goes off very slowly‚ or ends in a Swift movement; and it ends the same way it started‚ with noise. Noise‚ sound‚ our perception of both has changed since they were recognized and “categorized” as such. People see this soundscape

Lab Sheet 1. In the lab activity‚ you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you select the GO button‚ then the train will move) If the sound source is moving‚ as it get closer to the person it will get louder and the farther away it gets it starts to fade. 2.

The coming of sound was an innovation to cinema that forever changed the way films were produced‚ viewed and performed. Sound plays many roles in the way a film is narrated and perceived by the audience. Sound‚ as defined in the Oxford Dictionary of Film Studies‚ ‘is central to the way in which a film establishes setting‚ shapes character‚ signposts its narrative‚ directs the audience’s and instils general emotional states’ (2012: 385).
