Step-by-step explanation:
ANSWER:-
We know that
Tan²0 +1 = Sec²0
Placing value of Tan0 ,
Now we know that:
sec0 = 1/ cos0
cos0 = 21/29
Placing value in
Sin²0+cos²0=1
sin0 = 20/29
Now we know that sin0= 1/cosec0
So,
cosec0= 29/20
And also,
Tan0 = 1/cot0
Cot0 = 21/20
Note:-
0 in all angles refers to theta
