Question

If 3 cot A = 4, check whether
1 - tan? A.
1 + tan’A
cos? A-sinA or not.​

Answer 1

Step-by-step explanation:

3cotA = 4

cotA= 4\3

cotA=B/P

from here B =4 ,P=3

tanA=P/B =3/4

1+tanA =3/4+ 1

= 7/4

1 - tan A = 1- 3/4

= 1/4

in the hole question P stands for perpendicular B stands for base
