Question

what is the formula of Sin cube x​

Answer 1

Answer:

this is your answer

Step-by-step explanation:

sin X = opp / hyp = a / c , csc X = hyp / opp = c / a

tan X = opp / adj = a / b , cot X = adj / opp = b / a

cos X = adj / hyp = b / c , sec X = hyp / adj = c / b ,

acute angle trigonometric functions.Trigonometric Functions of Arbitrary Angles

sin X = b / r , csc X = r / b

tan X = b / a , cot X = a / b

cos X = a / r , sec X = r / a

acute angle trigonometric functions.

Special Triangles

Special triangles may be used to find trigonometric functions of special angles: 30, 45 and 60 degress.

Sine and Cosine Laws in Triangles

In any triangle we have:

1 - The sine law

sin A / a = sin B / b = sin C / c

2 - The cosine laws

a 2 = b 2 + c 2 - 2 b c cos A

b 2 = a 2 + c 2 - 2 a c cos B

c 2 = a 2 + b 2 - 2 a b cos C

Answer 2

Answer:

$sin3x = 3sinx - 4sin ^{3}x \\ sin3x - 3sinx = - 4sin ^{3}x \\ \frac{sin3x - 3sinx}{ - 4} = sin ^{3}x$
