simplify sin^2(x)+cos^2(x)+tan^2(x)

simplify

sin^{2} (x) + cos^{2} (x) + tan^{2} (x)

sec^{2} (x)

Solution steps

sin^{2} (x) + cos^{2} (x) + tan^{2} (x)

Rewrite using trig identities

= sec^{2} (x)

(x + 5) (x^{2} - 5 x + 25) - (x - 5) (x^{2} + 5 x + 25)

\frac{x ^{2} - x y}{x - y}

tan^{2} (x) - tan^{2} (x) sin^{2} (x)
