The graph of y-7 cosθ + 24 sinθ would be a sinusoid if it were plotted. What would be the first positive value of θ at which there is a high point?

From the graph, I get about θ=1.3
I assume you mean
y = 7 cos θ + 24 sin θ
well, my inclination is to look for where the derivative is 0
dy/dθ = -7 sin θ + 24 cos θ = 0
or
tan θ = 24/7 = 3.43
θ = 73.7 degrees
y = 7 cos θ + 24 sin θ
well, my inclination is to look for where the derivative is 0
dy/dθ = -7 sin θ + 24 cos θ = 0
or
tan θ = 24/7 = 3.43

yes, about 1.3 radians
