sin(x)= 1 csc(x) cos(x)= 1 sec(x) tan(x)= 1 cot(x) Warning: The reciprocal of sin(x) is csc(x), not sec(x). Note: We typically treat “0” and “undefined” as reciprocals when we are dealing with basic trigonometric functions. Your algebra teacher will not want to hear this, though! Quotient Identities tan(x)= sin(x) cos(x) and cot(x)= cos(x) sin(x) sin ^2 (x) + cos ^2 (x) = 1 . tan ^2 (x) + 1 = sec ^2 (x) . cot ^2 (x) + 1 = csc ^2 (x) . sin(x y) = sin x cos y cos x sin y (1 - sinx)/(1 + sinx) = (sec x - tan x)^2 About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features © 2021 Google LLC To solve sec x \sin ^{2} x=\sec x, do you divide each side by \sec x ?

2008-10-14 · Favourite answer. 1) put sec (x) = 1 / cos (x) 2) u have sin (x) in numerator and cos^2 (x) in denominator. 3) Now let cos (x) = t ------------eq (1) Take differentail on both sides of eq (3) U WILL have. - sin (x) dx = dt. Put this again in the original integrand. Bye.

cot 2 (x) + 1 = csc 2 (x). sin(x y) = sin x cos y cos x sin y. cos(x y) = cos x cosy sin x sin y Your expression may contain sin, cos, tan, sec, etc.

They are the basic tools of trigonometry used in solving trigonometric equations, just as factoring, finding common denominators, and using special formulas are the basic tools of solving algebraic equations.

Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. Integrating Products and Powers of sin x and cos x. A key idea behind the strategy used to integrate combinations of products and powers of \(\sin x\) and \(\cos x\) involves rewriting these expressions as sums and differences of integrals of the form \(∫\sin^jx\cos x\,dx\) or \(∫\cos^jx\sin x\,dx\).
