Please write it out so I can understand better, small comments help me understand even better. no cursive! i can't read cursive

Be sure to label cleanlyr your work with the problem number. angle restrictions for the inverse trigonometric functions are on the last page ( problem {la} , (lb) , [1c] [it'll , fie} , (if) 1 point each, (lg) 5 points , [1h] 3 points :I :I 1. For the sinusoidal function at) = all 40 ms (802: + 5?\") (a) the amplitude of f is equal to [la] the period of f is equal to [12} the frequency of f is equal to (d) the angular frequency of f is equal to [e] the phase shift of 3' from y = 50 4Dcos (30:17) is equal to {f} the horizontal shift of the graph of f from the graph of y = 50 4|] cos [802:] is (g) sketch a graph of f over one period, showing the exact location of quarter-cycle [quarter- period) points. (mast values for the z ooordinates should he in terms of fractions involving 7r, such as 37rf2ll, rather than decimal approximations) (h) nd all the solutions of the equation f (I) = 90
