Question

if cotA=12/5. find 3sinA+4cosA+1 / secA+cosecA​

Answer 1

Answer:

Step-by-step explanation:3sinA+4cosA+1/secA+cosecA

3sinA.1/cosA+4cosA.1/cosA+cosecA.secA

If cot=12/5

CosA/sinA =12/5

SinA/cosA=5/12

SinA=5cos/12

3.5/12+4+12/5cosA.1/cosA

5/4+4+12/5cos²A

21/4+5sec²A/12

21/4+5+5cot²A/12

21/4+5+144.12/5

(21+20)/4+1728/5

(205+6912)/20

7117/20
