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:-

SHOW THAT:-SIN²30° + COS²30° + TAN²30°

we know that:-

sin30=1/2

cos30=√3/2

tan45=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
