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∘)
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.
What is COS 120 in radians?
What is the value of tan?
By the trigonometry formula, we know, Tan (A – B) = (TanA – TanB) /(1 + Tan A Tan B) Hence, the value of tan (15°) is √3 – 1/√3 + 1.
