0 derivative of a constant is zero (sin(2X))'=cos(2X)*(2X)'=2*cos(2X) (sin(X))'=cos(X)Result is (29*sin(2X)*sin(X))'= 29*2*cos(2X)*sin(X)+29*sin(2X)*cos(X) You could also have cast your formula in the

Question about Algebrator - Algebra Homework Solver (689076614429)
...tan45 degrees solve for tan45 degrees using the identity tan(x/2)=sinx/1+cosx tan(x/2)=sin(x)/(1+cos(x)) Setting x/2=45, means that x=90 (degrees) But cos(90)=0 and sin(90)=1. Thus
cos(x)+1=0 This is a quadratic equation for the unknown U=cos(x) U^2-(5/2)U+1=0 Solve it by factoring or with the quadratic equation formula. The solutions are U=2 or U=1/2. Since U=cos(x), the root U
Question about BA II PLUS Financial Calculator
cos, I will always get 0, because using the 2nd before the cos turns the function into cos^-1 (inverse cosine). The inverse cosine of 1 is 0 because the cosine of 0 is 1. Good luck. Let me know if you
