Question

EXPRESS THE TRIGONOMETRY RATIOS sinA,secA, and tanAin term of cotA .

Answer 1

HELLO DEAR,


we know that:-

cosec²A=1+cot²A
=>cosec²A=√(1+cot ²A)-------(1)

and

sinA=1/cosecA

sinA=1/√(1+cot²A)-----using (1)

secA

we know that:-

1+tan ²A=sec²A

secA=√{1+ 1/cot ²A}

=>√(cot ²A+1)/cotA


tanA

we know that:-


tan A=1/cot A

I HOPE ITS HELP YOU DEAR,
THANKS
