Power of x. c = 0 x = 1 xn = n x(n-1)  Proof Exponential / Logarithmic ex = ex  Proof bx = bx ln(b)  Proof ln(x) = 1/x  Proof Trigonometric sin x = cos x  Proof csc x = -csc x cot x  Proof cos x = - sin x  Proof sec x = sec x tan x  Proof tan x = sec2 x  Proof cot x = - csc2 x  Proof Inverse Trigonometric arcsin x  =  1  (1 - x2)   arccsc x =  -1  |x| (x2 - 1)   arccos x =   -1  (1 - x2)   arcsec x =  1  |x| (x2 - 1)   arctan x =  1  1 + x2   arccot x =  -1  1 + x2   Hyperbolic sinh x = cosh x  Proof csch x = - coth x csch x  Proof cosh x = sinh x  Proof sech x = - tanh x sech x  Proof tanh x = 1 - tanh2 x  Proof coth  x = 1 - coth2 x  Proof	About the Author: mukeshpal.pal (29) Cool goIITian  5  [7 rates] total posts: 61     Offline
