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

simplify

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

cos (x) - cos (2 x)

Solution steps

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

(3 x + 2)^{2} + 2 (3 x + 2) - 3

(2 x + 3 y + 4 z)^{3}

(2 x^{4} y^{5})^{3}

(a - 2 b - 3 c)^{3}

∣ m o d x ∣ - 3
