化简 (sin^2(t))(5-(t^2))

解答

化简

(sin^{2} (t)) (5 - (t^{2}))

sin^{2} (t) (5 - t^{2})

求解步骤

(sin^{2} (t)) (5 - (t^{2}))

使用法则:

(a) = a

(sin^{2} (t)) = sin^{2} (t)

= sin^{2} (t) (5 - t^{2})

e x p an d e^{e^{x}} (e^{x} + e^{x - 1})

e x p an d \frac{( 40 - k ) ( 5 + k )}{45}

e x p an d (10 x^{4} - 11 x^{2} + 1)^{5}

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

e x p an d (2 + x + x^{4}) (5 x - \frac{1}{2 x ^{3}})^{8}
