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

simplify

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

2

Solution steps

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

Simplify

(- 2 sin (x))^{2} + (2 cos (x))^{2} : 4

= 4

Factor the number:

4 = 2^{2}

= 2^{2}

Apply radical rule:

a^{2} = a, a \geq 0

2^{2} = 2

= 2

\frac{2 x ^{- 2}}{3 x ^{- 3}}

\frac{42}{10}

3 b^{2} - 5 b - 2

62 \frac{43}{56} + 24 \frac{19}{20}
