Hint:
Here we need to know the properties and formula of the trigonometric function and we must know that and so we can use the calculator to solve for the value of trigonometric functions of any angle and then reciprocate them accordingly to get the value required.
Complete step by step solution:
Here we are given to find the way by which we can find of any angle on the calculator. We must know that we cannot find the value of to any angle directly on the calculator as it does not provide us with these functions. In the calculator we are displayed with the trigonometric functions of any angle and we need to use only these three trigonometric functions in order to find the value of to that angle.
Now we know that if we have the right angled triangle say right angled at
Let
Now we know that:
So we can see that
Hence in the calculator as we know that we have as the trigonometric functions so we can reciprocate according to the trigonometric function we require and we can get the value of
For example: If we want to find the value of so first we can see that in the calculator we can find the value of directly and after getting that value we can easily find the value of and we will get the value of
Note:
Here the student must know the trigonometric formula and properties in order to solve such problems. This problem is very simple if the student knows the way by which we can find the value of from
