  • Trigonometric functions are functions of an angle which are used to relate the angles of a triangle to the lengths of the sides of a triangle. For example, as depicted below, if we have a right triangle with one angle ΞΈ, having a as the opposite, b as the adjacent and c as the hypotenuse, then the following hold true.
    sinπœƒ=π‘Žπ‘ , cosπœƒ=𝑏𝑐 and tanπœƒ=π‘Žπ‘
    Write a program that takes the values of the lengths of the hypotenuse (c) and the adjacent (b) from a user and finds angle 𝜽 by passing these lengths to the function findAngle. After finding and returning the angle 𝜽, your program should covert the angle 𝜽 from degrees into radians using the formula shown below: π‘Ÿπ‘Žπ‘‘π‘–π‘Žπ‘›π‘ = πœ‹180Β°Γ—π‘‘π‘’π‘”π‘Ÿπ‘’π‘’π‘ 
    The calculated angle 𝜽 should then be displayed both in degrees and radians on the screen.
