Answer 1

Answer:

${ \sin(30) }^{2} + { \cos(30) }^{2} \\ = \frac{1}{4} + \frac{3}{4} \\ = 1$

${ \sec(45) }^{2} - { \tan(45) }^{2} \\ = { \sqrt{2} }^{2} - {1}^{2} \\ = 1$

${ \csc(60) }^{2} - { \cot(60) }^{2} \\ = { \frac{2}{ \sqrt{3} } }^{2} - { \frac{1}{ \sqrt{3} } }^{2} \\ = 1$

${ \sin(45) }^{2} + { \cos(45) }^{2} \\ \frac{1}{2} + \frac{1}{2} \\ = 1$
