## How do you find the value of cot?

The exact **value of cot**(60) is 1√3 . Multiply 1√3 by √3√3 . Combine and simplify the denominator. Multiply 1√3 1 3 and √3√3 3 3 .

What is the COT of 0 degrees?

In mathematics, any number divided by zero is undefined. Among the trigonometric ratios sin (°), cos (90°), tan (°) & **cot** (90°) are zeros. Their reciprocal ratios are indeterminate or undefined forms. Accordingly, cosec (°), sec (90°), **cot** (°) tan (90°) are indeterminate or undefined forms.

### What is the exact value of sin 240?

**sin** (**240**) = **sin** (60 + 180) = – **sin** 60.

### How do you find COS 240?

- 60∘ is an angle of one of the standard triangles with. cos(60∘)=12.
- 240∘ is in the 3rd quadrant so (either by CAST or noting that the “x-side” of the associate triangle is negative) cos(240∘)=−cos(60∘)
- cos(240∘)=−12.

### What is the secant?

[ sē′kănt′ ] A straight line or ray that intersects a curve, especially a circle, at two or more points. The ratio of the length of the hypotenuse in a right triangle to the side adjacent to an acute angle. The **secant** is the inverse of the cosine.
