Sep 16, 2020 ... sec x - tanx = (1/cosx) - (sinx/cosx) = (1-sinx)/cosx secx+tanx = (1+sinx)/cosx the product of the two is (1-sinx)( Mar 21, 2019 ... First, observe that sec^2(x) = 1 + tan^2 (x). Then substitute this for sec^2(x) in the formula: sec^2(x) + tan(x) = 1 1 + tan^2(x) + tan(x) You can put this solution on YOUR website! %28sinx%2Btanx%29%2F%281%2Bsecx%29=sinx tanx is the same as sinx%2Fcosx %28sinx%2B%28sinx%2Fcosx%29%29%2F%281 Ex: Solve 2sin.xtan.x-tan.x= 1-2 sin.x on the interval [0,2л). 2sinx tanx 1 tanx + 2sinx - 10 tanx (25inx-1) + 1(2 s/nx-1)=0 3π/Y.

DIFFERENCE IDENTITIES sin(x - y)=sin(x) cos(y) - cos(x) sin(y) cos(x - y) = cos(x) cos(y) + sin(x) sin(y) tan(x) ... 1. 1 y = tan(x) y. Sep 1, 2011 ... i.e. tanx = 1. This means (in this interval) that x = π/4. So π/4 is the only critical number. This means we have to check the points 0, π/4 ...
