Sec thada - Cos thada

How do I do this?

- Meaning what? -
**Damon**, Saturday, December 17, 2011 at 1:54pmThere is no equal sign so no identity.

sec t = 1/cos t

by definition if that helps

**Bosnian**, Saturday, December 17, 2011 at 2:58pmsec ( theta ) = 1 / cos ( theta )

sec ( theta ) - cos( theta ) =

[ 1 / cos ( theta ) ] - cos ( theta ) =

[ 1 - cos ^ 2 ( theta )] / cos ( theta ) =

sin ^ 2 ( theta) / cos ( theta ) =

sin ( theta ) * sin ( theta ) / cos ( theta ) =

[ sin ( theta ) / cos ( theta ) ] * sin ( theta ) =

tan ( theta ) * sin ( theta )
