1. Evaluate:

(i)

$\frac{tan \ 45^{\circ}}{tan \ 30^{\circ} + tan \ 60^{\circ}} =$

$\frac{\sqrt{i}}{i}$

(ii)

$sin^2 \ 45^{\circ} + cos^2 \ 45^{\circ} =$

2. Find the values of the following:

(i)

$(cos \ 0^{\circ} + sin \ 45^{\circ} + sin \ 30^{\circ})(sin \ 90^{\circ} - cos \ 45^{\circ} + cos \ 60^{\circ}) =$

$\frac{i}{i}$

(ii)

$tan^2 \ 60^{\circ} - 2 \ tan^2 \ 45^{\circ} - cot^2 \ 30^{\circ} + 2 \ sin^2 \ 30^{\circ} + \frac{3}{4} \ cosec^2 \ 45^{\circ} =$
