Question

How to calculate sec (π+θ)?

Answer 1

Answer:

-sec θ

Step-by-step explanation:

To find the value  sec (π+θ) need to put the values in the trignomtery axis.

Given: sec (π+θ)

Find: Need to find the final value of sec (π+θ).

Calculation:

It belongs to between the third and fourth quarter of the trignomatery equation.

The sec (π+θ=)-sec (-1+θ)

                       =-secθ

Answer 2

Concept

The trigonometric ratios are the ratios of the sides of a right angled triangle.

To find

Value of sec(π+∅)

Explanation

We know that in first quadrant all the trigonometric ratios are positive ,in second quadrant sin and cosec are positive , in third tan and cot are positive and in the last cos and sec are positive we know that π is equal to 180 and we have to divide it by 90 to find quadrant and it becomes 90*2+∅means it lies in third quadrant and the ratio does not change as 2 is even. So the value of sec (π+∅)=-sec∅.
