Question

the value of sin²90+cos²60/sec²45​

Answer 1

Answer:

we will just put the values

$\frac{1^{2} + (\frac{1}{1} )^{2} }{(\sqrt{2} )^{2} } \\ = \frac{1 + \frac{1}{4} }{2} \\ = \frac{\frac{4}{4} + \frac{1}{4} }{2}\\ = \frac{\frac{5}{4} }{2}\\ = \frac{5}{4} / 2\\ = \frac{5}{8}$

so the answer is 5/8
