simplify (cos^2(a))/(sin(a)+sin(a))

simplify

\frac{cos ^{2} ( a )}{sin ( a ) + sin ( a )}

\frac{cos ( a ) cot ( a )}{2}

Solution steps

\frac{cos ^{2} ( a )}{sin ( a ) + sin ( a )}

Add similar elements:

sin (a) + sin (a) = 2 sin (a)

= \frac{cos ^{2} ( a )}{2 sin ( a )}

Use the basic trigonometric identity:

\frac{cos ( x )}{sin ( x )} = cot (x)

= \frac{cos ( a ) cot ( a )}{2}

- (a + 3)^{2}

0.5 x - 1 y

p^{10} + p^{4} q^{6}

16 a^{4} - 4 a^{2} - 4 a - 1

2 x^{3} + 54 y^{3}
