Step-by-step explanation:
Answer:
Infinite number of solutions
Step-by-step explanation:

For any value of x, both equations are equal to each other because both sides are identical
Consider a<span> right triangle with </span><span>hypotenuse of 1.
sin x means to divide the side in front of the angle by </span>hypotenuse<span>
cos x means to divide the side beside the angle by hypotenuse
we know that a^2+b^2=c^2 now divide two sides by c^2

c is 1 also a/c means sinx and b/c is cos x so
sin^2(x)+cos^2(x)=1
