Question

The value of [(cos A / cot A) + sin A] is *

1 point

cot A

2 sin A

sec A

2 cos A

​

Answer 1

Answer:

2sin(a)

(cos(a)+sin(a)

=tan(a)cos(a)+sin(a)

=

cos(a)

sin(a)

(cos(a))+sin(a)

=sin(a)+sin(a)

=2sin(a)

Answer 2

cosA×1/cotA+sinA

1/cotA =tan A

cosA×tanA + sinA

tanA=sinA/cosA

cosA×sinA/cosA+sinA

sinA+sinA= 2sinA
