Solution

simplify

1 - cos^{2} (a)

Solution

sin^{2} (a)

Solution steps

1 - cos^{2} (a)

Use the Pythagorean identity:

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

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

= sin^{2} (a)

Popular Examples

simplify 2/(a+2)+1/a+(a-1)/(a^2+2a)simplify

\frac{2}{a + 2} + \frac{1}{a} + \frac{a - 1}{a ^{2} + 2 a}

factor x^{10}-10x^6+9x^2 factor

x^{10} - 10 x^{6} + 9 x^{2}

expand (x+4)(x+2)(x-1)(x-3)expand

(x + 4) (x + 2) (x - 1) (x - 3)

factor 27-125a^3-135a+225a^2 factor

27 - 125 a^{3} - 135 a + 225 a^{2}

simplify (-x+1/5-x^3)-(1/2 x-x^3-4/5)simplify

(- x + \frac{1}{5} - x^{3}) - (\frac{1}{2} x - x^{3} - \frac{4}{5})
