Question 619215: I am using a texas instrument TI-84 Plus calculator, the problem I would like answered is, find the value of the indicated trigometric function.
Find tangent theta, given secant theta = 1.3698
find tan theta, given sec theta = 1.3698

You can put this solution on YOUR website!
the secant is the inverse of the cosine

1/1.3698 will give you cos(theta)

there is also an identity ___ tan^2 = sec^2 - 1


either way should give the solution
