Write a program to receive value of an angle in degrees and check whether sum of squares of sine and cosine of this angle is equal to 1.
Write a program to receive value of an angle in degrees and check whether sum of squares of sine and cosine of this angle is equal to 1.
#include<stdio.h> #include<conio.h> #include<math.h> int main() { int degree, result; printf("Enter the degree of angle: "); scanf("%d", °ree); result = (sin(degree)*sin(degree) + cos(degree)*cos(degree)); printf("Result is: %d", result); return 0; }
Output:
Enter the degree of angle: 45
Result is: 1

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=ππ , cosπ=ππ and tanπ=ππ
Write a program that takes the values of the lengths of the hypotenuse (c) and the adjacent (b) from a user and finds angle π½ by passing these lengths to the function findAngle. After finding and returning the angle π½, your program should covert the angle π½ from degrees into radians using the formula shown below: πππππππ = π180Β°Γπππππππ
The calculated angle π½ should then be displayed both in degrees and radians on the screen.
