1) If \(tan(sin^{-1}A)=\frac{cos^2B(tan^4B-1)+1}{tan^2B}\)

Find the value of A.

 

 

 

 

 

2) If \((A+B)^2=\frac{\frac{2}{B}-1+\frac{\sqrt{2}}{B}}{(\frac{B}{A})^2}\)

Express the value of A and B in the form sin x and tan y respectively.

 

I made up these questions so the questions may not be possible to solve but there is at least 1 solution for each variables in the range 0 > (The variable) > 90 in degrees. Hope these are possible to solve.

MaxWong: Try and enter your questions into Wolfram/Alpha engine and see if it will give you the right answer here:http://www.wolframalpha.com/

I can't do it because I don't have Math keyboard. Just try it and see what you get.

Actually I don't want to know the answer, I have it.

I just want to know if my questions are possible to solve.

\(tan(sin^{-1}A)=\frac{cos^2B(tan^4B-1)+1}{tan^2B}\)

 

Hi Max,

If you enter it in a form that I can just copy and past then I will enter it into Wolfram Alpha for you :)

(that means  no   LaTex)

(1)      tan(asin A)=((cosB)^2((tanB)^4-1)+1)/(tanB)^2
