(3 arctan (x^{2}) + 5 sin (x^{2})) d x

3 arctan (x^{2}) d x + 5 sin (x^{2}) d x

求解步骤

(3 arctan (x^{2}) + 5 sin (x^{2})) d x

使用分配律:

a (b + c) = ab + a c

a = d x, b = 3 arctan (x^{2}), c = 5 sin (x^{2})

= d x \cdot 3 arctan (x^{2}) + d x \cdot 5 sin (x^{2})

= 3 arctan (x^{2}) d x + 5 sin (x^{2}) d x

e x p an d \frac{( x + 3 ) ( x ^{2} - 5 x + 6 )}{x ^{2} - x - 56}

e x p an d 2 t (4 π - t)

e x p an d 2 x (z x + x d z + z d x)

e x p an d cos (θ) 120 (cos (θ) + sin (θ))

e x p an d \frac{9 b ^{2} - 8 a}{12 ab}
