True
Note that:

The graph of sine and cosine functions are very similar. They only have a shift in the x -axis.
That is,  sin x  =  cos (90  -  x)
Since there is a great similarity between the sine and cosine graphs, and the secant graph is an inverse of the cosine graph, the graph of sine can be used to construct the graph of the secant function
Mathematically:
since  sec x  =  1 / cos x
and, cos x = sin (90 - x)
therefore, sec x = 1 / sin (90 - x)
The graphs of the sine and secant functions are attached to this solution

The formula of a continuous compound interest is
A=p e^rt
A future value?
P present value 1250
E constant
R interest rate 0.096
T time 12 years
A=1,250×e^(0.096×12)
A=3,955.64
