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

simplify

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

- cos (2 x)

Solution steps

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

Use the Double Angle identity:

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

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

= - cos (2 x)

3 (2 x + 1) + (3 + x) (x - 2)

\frac{5}{8} \div 2

x^{3} y^{2} - x y^{4}

3 i - 9 i + 10

\frac{6 - 25}{4}
