Let's simplify the expression step by step:
2cot(90) - 3cos(270) + 5sin(0)
cot(90) = 0, because cot(90) is the reciprocal of tan(90), and tan(90) is undefined.
So, the expression becomes:
2(0) - 3cos(270) + 5sin(0)
cos(270) = 0, because the cosine function is 0 at 270 degrees.
sin(0) = 0, because the sine function is 0 at 0 degrees.
So, the expression now is:
2(0) - 3(0) + 5(0)
0 - 0 + 0
0
Therefore, the simplified expression is 0.
