solvefor i,5sin(x)-2=3(1-sin(x))tan^2(x)

解答

求解

i, 5 sin (x) - 2 = 3 (1 - sin (x)) tan^{2} (x)

对所有 i 为真; 5 sin (x) - 2 = 3 (1 - sin (x)) tan^{2} (x)

求解步骤

5 sin (x) - 2 = 3 (1 - sin (x)) tan^{2} (x)

两侧相等

对所有 i 为真; 5 sin (x) - 2 = 3 (1 - sin (x)) tan^{2} (x)

so l v e f or y, (b) y = e^{5 x} tan (x^{2} + 2)

\frac{1}{1} + tan (x) + \frac{1}{1} - tan (x) = 4

\frac{tan ^{3} ( a )}{tan ( a )} = k

so l v e f or t, d^{2} \frac{u}{d ^{2}} v = tan^{2} (v) + 3

so l v e f or t, tan (27 0^{\circ} - a) = cot (a)
