Go! Here, we show you a step-by-step solved example of trigonometric identities. This solution was automatically generated by our smart calculator: Starting from the left-hand side (LHS) of the identity. Applying the secant identity: $\displaystyle\sec\left (\theta\right)=\frac {1} {\cos\left (\theta\right)}$.
if you multiply the equation by r^2, you get r^4 = 4r^2\cos 2\theta = 4r^2(\cos^2 \theta - \sin^2 \theta) = 4(x^2 - y^2) that is (x^2 + y^2 )^2 = 4x^2 - 4y^2 \to y^4+2y^2(x^2+2) +(x^4-4x^2). ... More Items
