Question 389693
Using exact values, find the value of: 
A.12sin 30 degree - 6 tan 45 degree + sec 45 degrees/ 52 
12*1/2 - 6*1 + √2/52 = √2/52
--------------------
B. Sin2A + tan3A/2 - cos A + sec(a+ 15)
Is it tan(3A/2), or (tan(A/2))^3 ?
----------

Sin2A + tan3A/2 - cos A + sec(a+ 15)= √3/2 + 1 - √3/2 + √2 = 1+√2
