expand sin(pi(t))-e^{-s}(sin(pi(t+1)))

expand

sin (π (t)) - e^{- s} (sin (π (t + 1)))

sin (π t) + e^{- s} sin (π t)

Solution steps

sin (π (t)) - e^{- s} (sin (π (t + 1)))

Remove parentheses:

(a) = a

= sin (π t) - e^{- s} sin (π (t + 1))

e^{- s} sin (π (t + 1)) = - e^{- s} sin (π t)

= sin (π t) - (- e^{- s} sin (π t))

Apply rule

- (- a) = a

= sin (π t) + e^{- s} sin (π t)

a (3 - 2 sin (θ))

3^{3 x + 2} - 9^{1.5 x} + (\frac{1}{27})^{- x - 1}

4 x^{3} d y + (3 x^{2} y - 3 x y) d x

(z^{3} + z^{4}) (7 x + \frac{2}{3})

- \frac{7 ( 2 x - 1 )}{( x - 5 ) ( x + 4 )}
