# Evaluate cos ( sin − 1 2 3 ) without using a calculator.

To determine

To calculate:

The value of given equation.

Explanation

Given Information:

cos(sin123)

Concept Used:

We find the value of given equation by using Pythagoras theorem: h2=p2+b2 and assuming the angle.

Calculation:

The given equation is:

cos(sin123)

Let sin123=θ

Therefore sinθ=23

As we know that sinθ=perpendicularhypotenuse

Perpendicular =2k & Hypotenuse =3k
