expand 1+tanh((k(t-a))/2)

expand

1 + tanh (\frac{k ( t - a )}{2})

1 + tanh (\frac{k t - ak}{2})

Solution steps

1 + tanh (\frac{k ( t - a )}{2})

\frac{k ( t - a )}{2} = \frac{k t - ak}{2}

= 1 + tanh (\frac{k t - ak}{2})

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

\frac{sin ( x ) + 1}{cos ( x ) ( sin ( x ) - 1 )}

\frac{d}{d x} ((3 x^{4} - 7) \times (5 x^{2} + 1))

(45 - x^{2} - 4 x + y^{2} + 2 y + 5)^{2}

(3 x + \frac{4.5}{x})^{8}
