expand (r+sin(θ)-cos(θ))dr

expand

(r + sin (θ) - cos (θ)) d r

r d r + sin (θ) d r - cos (θ) d r

Solution steps

(r + sin (θ) - cos (θ)) d r

Distribute parentheses

= d rr + d r sin (θ) + d r (- cos (θ))

Apply minus-plus rules

+ (- a) = - a

= r d r + sin (θ) d r - cos (θ) d r

\frac{( s ^{3} + 2 )}{s ^{2} \cdot ( s ^{2} + 4 )}

(x^{3} + x y^{2} - y) d x + (y^{3} + x^{2} y - x) d y

lo g_{10} (\frac{x y ^{2}}{z ^{8}})

\frac{x + 7}{( x + 3 ) ^{2}}
