Solve for x. (e^x-e^-x)/((e^x+e^-x)=t
Sergio [31]
\dfrac{e^x-e^{-x}}{e^x+e^{-x}}=t\\\\
\dfrac{e^{2x}-1}{e^{2x}+1}=t\\\\
e^{2x}-1=t(e^{2x}+1)\\\\
e^{2x}-1=e^{2x}t+t\\\\
e^{2x}-e^{2x}t=t+1\\\\
e^{2x}(1-t)=t+1\\\\
e^{2x}=\dfrac{t+1}{1-t}\\\\
e^{2x}=-\dfrac{t+1}{t-1}\\\\
2x=\ln\left(-\dfrac{t+1}{t-1}\right)\\\\
x=\dfrac{\ln\left(-\dfrac{t+1}{t-1}\right)}{2}\qquad t\in(-1,1)

Find the value of expression - 17x-19xpwer4 - 21x power 2,when x=3<br><br>​
Marrrta [24]

Answer:

-17x - 19x^4 - 21x^2 = -1779 when x = 3

Step-by-step explanation:

Given

-17x - 19x^4 - 21x^2

x = 3

Required

Solve

Substitute 3 for x in -17x - 19x^4 - 21x^2

-17x - 19x^4 - 21x^2 = -17*3 - 19*3^4 - 21*3^2

Evaluate all exponents

-17x - 19x^4 - 21x^2 = -17*3 - 19*81 - 21*9

-17x - 19x^4 - 21x^2 = -51 - 1539- 189

-17x - 19x^4 - 21x^2 = -1779
