expand cos(4t)h(t-(7pi)/4)

expand

cos (4 t) h (t - \frac{7 π}{4})

t h cos (4 t) - \frac{7 πh cos ( 4 t )}{4}

Solution steps

cos (4 t) h (t - \frac{7 π}{4})

= h cos (4 t) (t - \frac{7 π}{4})

Apply the distributive law:

a (b - c) = ab - a c

a = cos (4 t) h, b = t, c = \frac{7 π}{4}

= cos (4 t) h t - cos (4 t) h \frac{7 π}{4}

= t h cos (4 t) - \frac{7 π}{4} h cos (4 t)

Simplify

t h cos (4 t) - \frac{7 π}{4} h cos (4 t) : t h cos (4 t) - \frac{7 πh cos ( 4 t )}{4}

= t h cos (4 t) - \frac{7 πh cos ( 4 t )}{4}

lo g_{10} (1000) x^{4} y^{2}

\frac{x ^{3} + 4 ^{3}}{x + 4}

X^{2} - 10 X^{2} - 60

e^{s i n (x)} (cos^{2} (x) - sin (x))

(x^{2} - x + 1)^{6}
