Question 1188581
Calculate:

A)  Tan^2 225degrees-sin 60 degrees cos 30 degrees    ( don't understand what the Tan to the exponent 2 means)
----
It's the tan(225) squared
tan(225) = 1 ---> tan^2(225) = 1
-------
Use parentheses
A)  Tan^2(225)-sin(60)*cos(30) = {{{1 - (sqrt(3)/2)*(sqrt(3)/2)}}}
= 1 - 3/4 = 1/4
=======================
B) cos(45)*sin(225)+cos(330 = cos(45)*(-sin(45)) + cos(30)
