(Solved): Order the steps in proving the following identity: cos\lambda +sin\lambda tan\lambda =sec\lambda = ...
Order the steps in proving the following identity:
cos\lambda +sin\lambda tan\lambda =sec\lambda
=(cos^(2)\lambda )/(cos\lambda )+(sin^(2)\lambda )/(cos\lambda )
=(1)/(cos\lambda )
=cos\lambda +(sin^(2)\lambda )/(cos\lambda )
=(cos^(2)\lambda +sin^(2)\lambda )/(cos\lambda )
=sec\lambda
=cos\lambda +sin\lambda (sin\lambda )/(cos\lambda )Question 28 (4 points)
✓Saved Put the following proof in order using the left-hand side.:
(1-sinx)/(cosx)=(cosx)/(1+sinx)
=(cos^(2)x)/((1+sinx)(cosx))
=((1+sinx))/((1+sinx))((1-sinx))/((cosx))
=(cosx)/(1+sinx)
=(1-sin^(2)x)/(1)I hope I prdered these steps right but look at 27 please
