Question

state sine and cosine integral formula?​

Answer 1

Step-by-step explanation:

Some texts use ci instead of Ci. Ci(x) is the antiderivative of cos x / x (which vanishes as ). The two definitions are related by. Cin is an even, entire function. For that reason, some texts treat Cin as the primary function, and derive Ci in terms of Cin.

Answer 2

Sin, Cos and Tan

The sine of the angle = the length of the opposite side. the length of the hypotenuse.

The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.

The tangent of the angle = the length of the opposite side. the length of the adjacent side.
