Simplify the following without using tables.
Note: `root`𝑎`times``root`𝑎 = a
(a) sin 30° cos 30°
(b) 4 cos 45° sin 60°
(c) 3 cos 30° + cos 60°
(d) tan 45° + cos 45° sin 45°
(e) sin 60° cos 30° + Sin 30° cos 60°
(f) `cos^2`60°+`sin^2`60° (sin `theta` `times` sin `theta` is written as `sin^2``theta`)
