Question

If 3 cot A = 4 then find the value of Cosec2A +1 / Cosec2A – 1

Answer 1

I hope it help u........

Answer 2

Concept introduction:

An angle is a geometry in trigonometry that is created by two vectors or lines that have a shared termination. The Latin word "angulus," which meaning "corner," is the source of the English term "angle."

Given:

Here it is given that $3 cot A = 4$.

To find:

We have to find  the value of $Cosec2A +1 / Cosec2A - 1$.

Solution:

According to the question,

By the angle rule we can found that $AB=3, BC=4$.

Now, $AC= 5$,

Putting the value we can get $cosec A=5/3$.

So, the answer of the following equation is $13/7$.

Final answer:

So, the final answer of the question is $13/7$.
