Simplify the expression by first substituting values from the table of exact values and then simplifying the resulting expression. (tan 45° + tan 60°)^2

Still trying to figure this one out Lizzie May?

OpenStudy (liziekay):

yep

OpenStudy (liziekay):

wouldn't tan 45 degrees for the exact value be 1 and tan 60 degrees be square root 3?

zepdrix (zepdrix):

Mmm yes good :)

zepdrix (zepdrix):

$\large\rm (\tan45+\tan60)^2=(1+\sqrt3)^2$

OpenStudy (liziekay):

yes exactly

zepdrix (zepdrix):

And I guess they want you to expand out the square from that point.
