The exact value of csc(π4) csc ( π 4 ) is √2 .

Also asked, what is the value of Cot Pi by 4?

Make the expression negative because cotangent is negative in the fourth quadrant. The exact value of cot4) cot ( π 4 ) is 1 .

Beside above, what is the value of π in trigonometry? The pi value is an irrational number approximately equal to 3.1416. This value is used in geometry to define the area and volume of curvilinear shapes and solids. The area of a circle is pi times the radius squared. The volume of a sphere is pi times four-thirds times the radius cubed.

## What is pi minus theta?

Pi minus theta is the supplement of theta. Sine pi, cosine theta, cosine pi, sine theta and with sine the minus stays the same. The sine of pi 0, cosine of pi is -1, so it turns out that the sine of pi minus theta is equal to the sine of theta.

## Why is PI 180 degrees?

Pi doesn't equal any number of degrees because pi without a unit is just a number. The point is that pi radians is equal to 180 degrees. Radians are a unit of measurement for angles, just like degrees are, and pi is just the number of radians that makes up that angle.

## How do you convert COS to tan?

Express Sine in Terms of Tangent
1. Start with the ratio identity involving sine, cosine, and tangent, and multiply each side by cosine to get the sine alone on the left.
2. Replace cosine with its reciprocal function.
3. Solve the Pythagorean identity tan2θ + 1 = sec2θ for secant.
4. Replace the secant in the sine equation.
