Kay's Math: Solve trigonometric equations- IB / A/AS Levels/ CBSE/ ICSE

Solve the following equations in the domain $0\leq x\leq 2\pi$

$\\ \blacklozenge \;\;\; tan^{2}x=3 \\ \\ \blacklozenge \;\;\; sin^{2}x+ 2 sin x + 1 = 0 \\ \\ \blacklozenge \;\;\; tan^{3}x+ tan x = 0 \\ \\ \blacklozenge \;\;\; sin x + csc x = 1 \\ \\ \blacklozenge \;\;\; sec x - cos x = 0$

$\\ \blacklozenge \;\;\; tan^{2}x=1 \\ \\ \blacklozenge \;\;\; cos^{2}x+ 2 cos x + 1 = 0 \\ \\ \blacklozenge \;\;\; sin^{3}x+ sin x = 0 \\ \\ \blacklozenge \;\;\; (1- sin x)(1 + sin x)=0 \\ \\ \blacklozenge \;\;\; 2 sin^{2}x + sin x - 1 = 0$
