Take this trigonometric function:
Using the chain rule i think it becomes:
But if we use the identity:
then the equation becomes
But if,
then,
Which doesn't appear so. Why am I getting different answers for the same derivative? Did I do something wrong in the above steps?
I accidentally took :
P.S. This is my first post and using [tex] is VERY slow and irritating, is there a faster way to insert math expressions
I Can't belive i was so stupid. I hadn't been doing trig for a long time so i messed up when I took:
By the way, any have a answer to my P.S.:
