Assume that playing soccer requires 540 calories per hour. On a particular day, you ate 2,000 calories in food. You played soccer for 2.5 hours. We have cot 3x = cot (2x+x). ⇒(cot 2x cot x)-1cot 2x + cot x. ∴ cot 3x (cot 2x+ cot x)= (cot 2x. cot x)-1. ⇒ cot 3x . cot 2x+ cot 3x . cot x = (cot 2x . cot x) ... cot2k+1(x)=(−1)kcot(x)+csc2(x)k ... 1(x)cot(x)dx. dv=csc2(x)dx. then v=− ... The period of the cot(x) cot ( x ) function is π π so values will repeat every π π radians in both directions. x= ...

Hint: Use the identity sin2 x + cos2 x = 1. Sol. /. 1 sin2 xcos2 x dx ... (tanx − cotx + C) = sec2 x + csc2 x. • Find f by solving the initial value ... tan(-x) = - tan(x) cot(-x) = - cot(x). PYTHAGOREAN IDENTITIES cos2(x) + sin2(x)=1 tan2(x)+1 = sec2(x) cot2(x)+1 = csc2(x). SUM IDENTITIES sin(x + y)=sin(x) ... In the computation of FPS(atan(cot(x)),x,0), REDUCE is not able to ... df(y,x,3)*(x - 1) + 3*df(y,x,2)*x + df(y,x). SimpleDE(exp(x^(1/3)),x) gives. 2.
