Question

Q) cotA tanA (1)

a)tanA
b)secA
c)1
d)cotA​

Answer 1

cot A tanA =

$tan \: a \: = \frac{ \sin }{ \cos}$

$cot \: a = \frac{ \cos }{ \sin }$

ans=

$\frac{ \sin }{ \cos } \times \frac{ \cos }{ \sin }$

answer = 1

option c is the answer

Answer 2

Step-by-step explanation:

cot A - tan A

cosA- sin A

sin A

cos square A- sin square A

sinA cosA

cos square A-(1-cos square A)

sinA cosA

2 cos square A-1

sinA cosA
