simplify (rcos(θ))(rsin(θ))

Solution

simplify

(r cos (θ)) (r sin (θ))

Solution

r^{2} cos (θ) sin (θ)

Solution steps

(r cos (θ)) (r sin (θ))

Remove parentheses:

(a) = a

= r cos (θ) r sin (θ)

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

rr = r^{1 + 1}

= cos (θ) r^{1 + 1} sin (θ)

Add the numbers:

1 + 1 = 2

= cos (θ) r^{2} sin (θ)
