Question

if sin A=3/5 and A is not in first quadrant find secA -tanA/cosecA + cot A​

Answer 1

Step-by-step explanation:

cos=,√1-sin*2A. here formula idont know how to write sin square so I wrote like that

cosA=4/5

secA=1/cosA

=1/4/5

=5/4

tanA=sinA/cosA

=3/5/4/5=3/5*5/4 =3/4

cosecA=1/sinA

=1/3/5=5/3

cotA=cosA/sinA=4/5/3/5=4/3

secA-tanA/cosecA+cotA=5/4-(3/4/5/3)+4/3

=5/4-9/20+4/3=113/20
