Question

Show that sin2(30)+sec2(30)+tan2(45)=2

Answer 1

HELLO DEAR,

i think something is mistake in your questions,

right questions is like that:-

sin²(30°) +cos²(30°) +tan²(45°) = 2

we know that:-

sin(30°) = 1/2

cos(30°) = √3/2

tan(45°) = 1

${ (\frac{1}{2}) }^{2} + { (\frac{ \sqrt{3} }{ 2}) }^{2} + {(1)}^{2} \\ \\ = \frac{1}{4} + \frac{3}{4} + 1 \\ \\ = \frac{4}{4} + 1 \\ \\ = 1 + 1 = 2$
I HOPE ITS HELP YOU DEAR,
THANKS
