Question

4 (sin4 60° + cos4 30°) - 3 (tan2 60° - tan2 45°) + 5 cos2 45°​

Answer 1

Answer:

4((\frac{\sqrt{3} }{2} )^{4} + $(\frac{\sqrt{3} }{2} )^{4}$) - $3(\frac{√3}{\sqrt 3} ^{2}- 1^{2} )$ + $5( 1/√2[tex]</p><p>=4(\frac{9}{16}+\frac{9}{16}) - 3(3 - 1) + 5(\frac{1}{2} )$^{2} )[/tex]

do the rest of the calculation on your own
