arc tan|tanx|= |x|  true or false?

6 years ago


Answers : (1)


1) take angle as  x=135


arc tan|tanx| = arc tan|tan135|= arc tan|-1|=  arc tan(1) = 45

|x|=135     WHICH IS NOT CORRECT so it is not True


true only in the   1st cordinant that is from [0, pi/2] and the fourth

the range of tanx is between [-90,90] so it is not true in 3 quadrants

If a+b+c=0,then the family of lines 3ax + by + 2c = 0 pass through the fixed point
Dividing the whole eqn. by 2 and comparing with a+b+c = 0 3ax + by + 2c = 0 we get, 3a/2 x + b/2 y + c = 0 3x/2 = 1 x = 2/3 and y/2 = 1 y = 2. hence (x,y) that is (2/3 , 2) is the fixed...

Write I = dx/x.(x^2n-a^2n)^1/2 = dx/x.(x^n + a^n)^1/2.(x^n – a^n)^1/2 = A/x + B/(x^n + a^n) + C/(x^n - a^n) Solve it by partially no. n is actually pi in image check it again plz.
