For the function f(0)=sin(0), <u>0 is the input variable</u> while f(0) is the output.
For the function g(0)=cos(0), <u>0 is the input variable</u> while g(0) is the output.
The standard form of representing trigonometry functions is f(x) = sinx or f(x) = cos x
From the functions:
- x is the input variable (also known as the domain)
- y is the output variable also known as the range;
Given the trig function f(0)=sin(0), compared with the general equation, we can see that 0 is the input variable while f(0) is the output.
Similarly for the function g(0)=cos(0),<u> 0 is the input variable</u> while g(0) is the output.
