Question

Show that (sin square 45- tan square 45)square + 3(sin square90 + tan square30) =17/4.

Answer 1

Answer:

$(({ \frac{1}{ \sqrt{2} } })^{2} - 1)^{2} + 3(1 + { (\frac{1}{ \sqrt{3} })^{2} }) \\ ( \frac{1}{2} - 1)^{2} + 3(1 + \frac{1}{3}) \\ ( \frac{ - 1}{2} )^{2} + 3( \frac{4}{3} ) \\ \frac{1}{4} + 3( \frac{4}{3} ) \\ \frac{1}{4} + {4} \\ \frac{1 + 16}{4} \\ \frac{17}{4}$
