y=sinx

y=sinx : In mathematics, the trigonometric functions (also called circular functions) are functions of an angle. They are used to relate the angles of a triangle to the lengths of the sides of a triangle. Trigonometric functions are important in the study of triangles and modeling periodic phenomena, among many other applications. The most familiar trigonometric functions are the sine, cosine and tangent. The sine function takes an angle and tells the length of the y-component (rise) of that triangle. The cosine function takes an angle and tells the length of x-component (run) of a triangle. The tangent function takes an angle and tells the slope (y-component divided by the x-component). More precise definitions are detailed below. Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angle, and can equivalently be defined as the lengths of various line segments from a unit circle. More modern definitions express them as infinite series....   More from Wikipedia

y=sinx : In physical chemistry, Electron Phases describe the sign (positive or negative) of the wave function, which is a solution to the Schrödinger equation. When two wave functions describing two atomic orbitals on the same atom are combined, a hybrid orbital is created. When wave functions for..   More from Wikipedia

  The sin graph

  problems still Get out my trig chart Cuz im scared to graph without it I gotta graph without it that's what they talk about it There aint no work about it See all these numbers round it Lotta shifts happenin round me Going down the line like Ghandi y=Sinx-2 Start at Pi/2 Move it right by 2 What you got brand new This graph is to the right Phase shifted for you Man I got something cool I learned all this at school I scratch work ..so I don't go berserk I got distribution so im Convertin' ...

Question : I want to know translation of y =sinx+cosx from y = A sinx. I really need to do it as quick as possible. So, please answer me !!!!!!!!!!!!!!

Answer : There is a standard method for y = A sin x + B cos x you chose A = r cos t B = r sin t then square both sides and add r^2= A^2 + B^2 devide to get tan t = B/A so y = r (sin x cos t + cos x sin t) = r sin (x+ t) in the current case A = 1 ans B = 1 so r = sqrt(2) and tan t = 1 or t = pi/4 so sin x + cos x = sqrt(2) sin (x+ pi/4)..   More from Yahoo Answers

Question : I have to find the local max and min of that function, so I need to solve for x. How do you solve for x in y' = -sinx + cosx

Answer : y' = -sinx + cosx Just integrate: y = cosx + sinx + y0 ; calling C=y0 (y -y0) = cosx + sinx [You can maybe determine from your problem whether constant of integration C = y0, or 0, or whatever. But let's solve the general case.] Now note cosx + sinx = 2 (1/ 2 cosx + 1/ 2 sinx) = 2 (sin( /4) cosx + cos( /4) sinx) = 2 sin(x + /4) (y -y0) = 2 sin(x + /4) ( (y -y0)/ 2 ) = sin(x + /4) arcsin ( (y -y0)/ 2 ) = x + /4 x = (arcsin ( (y -y0)/ 2 )) - /4 ANSWER..   More from Yahoo Answers
