Find the values of the other five trigon...

Find the values of the other five trigonometric functions I each of the following: `cottheta=(12)/5,theta` in quadrant III

Text Solution

Verified by Experts

We have,
`cosec^{2} theta-cot ^{2} theta=1 `
`Rightarrow cosec^{2} theta=1+cot ^{2} theta `
`Rightarrow cosec theta=pm sqrt{1+cot ^{2} theta}`
