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

simplify

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

cos (x) + 1

Solution steps

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

Use the Pythagorean identity:

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

= cos (x) + 1

3 \cdot lo g_{a} (2) + 2 \cdot lo g_{a} (3)

(- 2 x + 7)^{2} - (3 x - 6) + 4 x

\frac{( x ^{- 3} )}{( x ^{3} )}

8 x y^{2} - 18 x y

(6 x - y)^{3} - (6 x + y)^{3}
