1.	if sin theta equal to cos theta then 2 tan square theta + sin squared theta -1 is equal to options number 1 : -3/2, no.2 : 3/2,no.3 : 2/3, no.4: -2/3. EXPLAIN HOW TBE ANSWER COMES BRIEFLY.
Answer» ANSWER: sinØ=cosØ sin45°=cos45°=1/√2 Ø=45° then, 2tan²Ø+sin²Ø-1 =2(1)²+(1/√2)²-1 =2(1)+1/2-1 =2+1/2-1 =(4+1-2)/2 =3/2 no.2 —3/2 is correct. Hope it WORKS...................................™✌️✌️

Answer»

ANSWER:

sinØ=cosØ

sin45°=cos45°=1/√2

Ø=45°

then,

2tan²Ø+sin²Ø-1

=2(1)²+(1/√2)²-1

=2(1)+1/2-1

=2+1/2-1

=(4+1-2)/2

=3/2

no.2 —3/2 is correct.

Hope it WORKS...................................™✌️✌️
