Trigonometric identities hard question

AI Thread Summary
The discussion focuses on simplifying the expression sin(b)/cos(b) + cos(b)/sin(b). Participants confirm that the initial transformation to tan(b) + cot(b) is correct but not the final simplification. The key suggestion is to use a common denominator to combine the fractions, which leads to a more surprising result. Ultimately, the expression simplifies to 1/(cos(b)sin(b)). Understanding this method is essential for tackling similar trigonometric identity problems effectively.

Simplify the following:
sin(b)/cos(b) + cos(b)/sin(b)


Homework Equations



Trigonometric identities

The Attempt at a Solution


Ok so i have no clue how to do this,I keep trying but can't seem to get the right answer, I have tried to do this:

sin(b)/cos(b) + cos(b)/sin(b)
=tan(b)+ 1/tan(b)
=tan(b)+cot(b)

I know this isn't right and I am encountering these types of questions quite often now, so I really need help. Please help me.

Well, it is true that sin(b)/cos(b) + cos(b)/sin(b) = tan(b) + cot(b) , but you probably need to come up with something more surprising.


Use a common denominator to combine sin(b)/cos(b) + cos(b)/sin(b) into one fraction. Yo may be surprised by what the numerator simplifies to.
 
yeah I know it's just that the answer is 1/cos(b)sin(b). How would I get to this?

As I said before,
se a common denominator to combine sin(b)/cos(b) + cos(b)/sin(b) into one fraction.​
