amplitude of f(t)=3cos(4t-(3pi)/4)+2

amplitude

f (t) = 3 cos (4 t - \frac{3 π}{4}) + 2

3

Solution steps

f (x) = 3 cos (4 t - \frac{3 π}{4}) + 2, A = 3

Therefore, the amplitude |A| is

3

3

\frac{x - 1}{x + 1}

\frac{x - 1}{( x - 6 ) ( x + 8 )}

x^{2} + 6 x

f (x) = \frac{- 5 x - x ^{3} - 2}{x ^{3} - 3 x ^{2} + 5}

\frac{x + 4}{x ^{2} + 5 x + 4}
