(7-xsin(a))*(xsinx(a)-1)
Sorry....I don't understand what the term xsinx(a) means.......???
I need to derivative a difficult function where there's several unknown units. And to go forward I need to simplify that. It's called times sinus of a.
I found it to be 6-x^2*sin^2a but been told it's wrong
kind of hard aint it
