sin^2 theta + 2 cos theta -1/ (sin^2 theta +3 cos theta-3= cos^2 theta+cos theta/ (-sin^2 theta) Prove the identity
prove the identity: sin^2 O/ 1-cos O = 1+cosOO= theta
prove the identity : cos^4 theta- sin ^4 thetaover sin squared theta cos squared theta =cot squared theta - tan squared theta
prove the identity cos theta sec theta/cot theta = tan theta
Prove that Sin(theta)times Cos(theta) divided by Cos^2(theta)-Sin^2(theta)=Tan(theta) divided by 1-Tan(theta) Show step by step how to change the left to equal the right side of equasion
if cos 2 theta = -(1/3) and theta is in Quadrant 2, find sin theta, cos theta, tan theta, and draw triangle theta
So apparently I have forgotten all of my undergrad maths, trying to solve the following equation for theta #1/2 = cos^2(2*pi*sin(theta)) # . I know it must be an identity I have forgotten, but I cannot seem to find it online.
prove the following identitycos^4X - sin^4X = 1-2sin^2X
Sin theta - 2 cos theta sin theta = 0
If cos theta = -sin theta,then sin^2 theta is what?
#(2+sqrt3)cos theta=1-sin theta#
