Apr 15, 2012 · Remember that tanx = sin x/ cos x. So sin x + cos x(cos x / sin x) (You flip sin x and cos x since tan x is dividing cos x) Then take the lcm of sin x and the equation becomes . Sin^2x + cos^2x whole divided by sin x. Remember that Sin^2x + cos^2x=1 . Thus it's equal to 1/sin x :) Oct 20, 2009 · Multiplying both sides of the equation by sinx(1 + cosx), (sinx)^2 + (1 + cosx)^2 = 2sinx(1 + cosx)(cscx) Substituting 1/sinx for cscx and simplifying Oh, well, if $f(x)=\arccos(\sin x)$, then [math]f^\prime(x)=\dfrac{-1}{\sqrt{1-\sin^2x}}\cos x=-\dfrac{\cos x}{\lvert\cos x\rvert}=\begin{cases} 1 & \cos x Apply substitutions to transform the identity. \begin{align} E &= \tan x(\cot x - \cos x) && \bigg\{ \textrm { Substitute: } \quad \tan (x)= \frac{\sin (x)}{\cos (x You need to multiply both sides by cos^2 x such that: 1-2sinx-3sin^2x = cos^2 x(1-3sinx)/(1-sinx)  You need to multiply both sides by (1-sinx) such that: Question 885227: How do you solve 1-sinx=cos2x Answer by lwsshak3(11628) (Show Source): You can put this solution on YOUR website!
