Question

tan^2 60°+ 4cos^2 45° + 3 sec 30°+ 5cos^2 90°/cosec 30° + Sec 60° - Cot^30°​

Answer 1

Answer:

=(√3)^2 + 4(1/√2)^2 + 3(2/√3) + 5(0)^2/2 + 2 - √3

=3 + 2 + 2√3 + 0 + 2 - √3

=7 + 2√3 - √3

=7+√3

Answer 2

$\sf \frac{tan²60°+4cos²45°+3sec²30°+5cos²90°}{cosec30°+sec60°-cot²30°}$

$\sf \frac{{(√3)}^{2}+4×({\frac{1}{√2})}^{2}+3× {(\frac{2}{√3})} ^{2}+5× {(0)}^{2} }{2+2-{(√3)} ^ {2}}$

$\sf \frac{3 + 2 + 4 + 0}{2 + 2 - 3}$

$\sf \frac{9}{1}$

$\sf 9$
