inverse of cos(2pit)

Solution

inverse

cos (2 π t)

Solution

\frac{arccos ( t )}{2 π}

Solution steps

cos (a) = b \Rightarrow a = arccos (b)

2 π t = arccos (y)

Solve for

t, 2 π t = arccos (y)

\frac{arccos ( y )}{2 π}

Substitute

y = t

\frac{arccos ( t )}{2 π}

f (x) = - 0.75 x

domain of f(x)=(x^3)/(x^2-1)domain

f (x) = \frac{x ^{3}}{x ^{2} - 1}

inverse of f(x)=sqrt(3x+5)inverse

f (x) = 3 x + 5

inflection y=-x^4-5x^3+6x+7 inflection points

y = - x^{4} - 5 x^{3} + 6 x + 7

perpendicular y=x+3 perpendicular

y = x + 3
