Question

If sec thita + tan thita =2/3 , find the value of sin thita and determine the quadrant in which thita lies

Answer 1

Answer:

We are given that sec theta + tan theta = 2/3 and we have to determine the value of sin theta. Now, cross multiplying the fractions we get; Since the value of is negative, this means that theta will lie in 3rd and 4th quadrant because in these two-quadrants sin values are negative.

Here's your answer
