Question

HEEEEEELLLLPPPP MEEEE!!
The equation of a sine function with amplitude of 8 and period 45 degrees is ?

Answer 1

@satellite73

Answer 2

HELP PLEASE

Answer 3

y = a Sin bx That is the general form for a sine function without a phase shift, Your problem does not mention a phase shift. So that is it. The a is for the amplitude........What is the given amplitude?

Answer 4

also which equation can be used to fin the max value of the s

Answer 5

8 is the amplitude

Answer 6

and 45 degrees is the period

Answer 7

Yes so we start with y = 8 Sin b x
b is for the period and is equal to (2 Pi)/b. Since the period is given as 45 degrees convert that in terms of pi, Here is how I remember how to do that, 180 degrees = 1 Pi,
90 degrees = 1/2 Pi so 45 degrees must be 1/4 Pi since the period = (2 Pi)/b we have this situation: we now can complete the equation;
y=8 Sine 2x
