Question

if cosec a minus cot a equal kooda to 3 then find the value of cosec A + cot a​

Answer 1

Answer:

It is given that 4cotA=3

Thus cotA=43=PB

P=4, B=3

Now, H2=P2+B2

H2=32+42

H2=52

H=5

cosec2A−cot2A=(PH)2−(PB)2 

= (45)2−(43)2

= 1625−169

= 1616

= 1

Answer 2

Answer:

Cosec A - Cot A=3

then Cosec A+Cot A=?

Answer

cosec²A - cot²A =1

therefore, (Cosec A - Cot A)(CosecA+Cot A)=1

so (CosecA + Cot A)=1/(Cosec A - Cot A)

so Cosec A +Cot A =1/3
