Unformatted text preview: double exp(double); /* e to the power */ exp(2.4) = e 2.4 exp ( log ( 53.2)) = 53.2 log ( exp (17.1)) = 17.1 double pow(double b, double c); /* b to the c */ b c double sqrt(double) You can't take the square root of a negative number. Therefore, you can't do pow(-3.0, 0.5); sqrt(-3.0) ; (If you try pow(-3.0, 1/2) you get 1.0, because pow(-3.0,1/2) = pow(-3.0, 0.0) = 1.0 )...
