tan^1(a) signifies the arctangent function, the function that returns the angle for a given tangent value of a.
tan(a)^-1 signifies the reciprocal of the tangent function, which is the definition of the cotangent function.
The attached graph compares the two functions.
Answer:
16
Step-by-step explanation:
Simplify the following:
4 + 3×2^3/2
3×2^3/2 = (3×2^3)/2:
4 + (3×2^3)/2
Combine powers. (3×2^3)/2 = 3×2^(3 - 1):
4 + 3×2^(3 - 1)
3 - 1 = 2:
4 + 3×2^2
2^2 = 4:
4 + 3×4
3×4 = 12:
4 + 12
4 + 12 = 16:
