Tell whether or not f(x) = 3 sin 2 - cos x is a sinusoid.

Answer

b. No

Step-by-step explanation:

We can easily solve this question by using a graphing calculator or any plotting tool, to check if it is a sinusoid.

The function is

f(x) =  3*sin(2*x) - 5*cos(x)

Which can be seen in the picture below

We can notice that f(x) is a not sinusoid. It has periodic amplitudes, and the function has a period T = 2π

The maximum and minimum values are

Max = 6.937

Min = -6.937

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
