simplify-cos^2(t)-sin^2(t)

simplify

- cos^{2} (t) - sin^{2} (t)

- 1

Solution steps

- cos^{2} (t) - sin^{2} (t)

Use the Pythagorean identity:

cos^{2} (x) + sin^{2} (x) = 1

- cos^{2} (x) - sin^{2} (x) = - 1

= - 1

\frac{175 x ^{8}}{7}

\frac{\frac{9}{27 x - 9}}{\frac{1}{( 12 x - 4 )}}

x^{2} x^{5}

(- 3 x^{2} + 2 x - 4) + (4 x^{2} + 5 x + 9)

\frac{y - 3}{( y - 5 ) ^{2}} - \frac{y - 2}{y ^{2} - 4 y - 5}
