$\frac{1+\tan\left(a\right)^2}{\csc\left(a\right)^2}+\sin\left(a\right)^2+\cos\left(a\right)^2$
Learn how to solve problems step by step online. Simplify the trigonometric expression (1+tan(a)^2)/(csc(a)^2)+sin(a)^21/(sec(a)^2). Applying the trigonometric identity: \displaystyle\frac{1}{\sec^{n}(\theta)}=\cos^{n}(\theta). Applying the pythagorean identity: \sin^2\left(\theta\right)+\cos^2\left(\theta\right)=1. Applying the trigonometric identity: 1+\tan\left(\theta \right)^2 = \sec\left(\theta \right)^2. Simplify \frac{\sec\left(a\right)^2}{\csc\left(a\right)^2} using trig identities.
