Best ResponseYou've already chosen the best response.12^(x+1) = 2. 2^x , 4^x = (2^x)^2 plug in 2^x = tan y and see the magic! (simplification :P)

Best ResponseYou've already chosen the best response.1same thing....tan 2 thetha comes from tan (x+y) formula only

Best ResponseYou've already chosen the best response.1with substitution, you would have got the same thing...

Best ResponseYou've already chosen the best response.1@Abhishek619 @hartnn answer is [2^(x+1)loge2]/(1+4^x) :'(

Best ResponseYou've already chosen the best response.1i am never interested in final answer, just the method..... if your algebra part is correct, you WILL get correct final answer....

Best ResponseYou've already chosen the best response.1but the answer is in loge2 and having (1+4^x) also

Best ResponseYou've already chosen the best response.1well did he wrote 2tan^12^x?????????

Best ResponseYou've already chosen the best response.1ok, got till 2 tan inverse 2^x, right ? if you diff. that u get 2 * (1/1+(2^x)^2) 2^x ln 2 (ln = log_e) .... (2^x ln 2 comes from chain rule) yes...

Best ResponseYou've already chosen the best response.1yeah... (2^x)^2 = 4^x and 2.2^x = 2^(x+1) good!
