USING TRIGONOMETRIC VALUES Table:
1.Evaluate cot (30°) + tan(60°).
.
2.Multiply sin (90°) by csc(150°)
.
3.Find sec (60°) - tan(225°)
[tex]3.) \sec( {60}^{0} ) - \tan( {225}^{0} ) \\ 2 - \tan( {225}^{0} ) \\ 2 - 1 \\\red{\boxed{1}} [/tex]
[tex]4.) { \sin }^{2} ( {210}^{0} ) + { \cot }^{2} ( {270}^{0} ) \\ - \frac{1}{2} + \cot( {270}^{0} ) \\ - \frac{1}{2} + 0 \\ \red{\boxed{ - \frac{1}{2} }}[/tex]
