Question

Given root2 Sin A=1 calculate tan A,sec A, CosA and 2× cosA× sinA

Answer 1

Step-by-step explanation:

2SinA=1

SinA=1/√2 which is equal to perpendicular /hypotenuse

therefore , perpendicular =1 and hypotenuse = √2

By pythagoras theorem

H^2=P^2+B^2

√2^2=1^2+B^2

2=1+B^2

1=B^2

therefore ,√1=B

TanA=P/B

=1/√1

SecA=H/B

=√2/√1

CosA=B/H

=√1/√2
