Express the trigonometric ratios sin A, sec A and tan A in terms of cot A
sinA can be expressed in terms of cotA as:
1/(√cosec2A)
= 1/√(1 + cot2A)
Now,
Sec can be expressed in terms of cot A as:
secA = √sec2A
= √(1 + tan2A)
= √[1 + (1/cot2A)]
= √[(1 + cot2A)/cot2A]
= [√(1 + cot2A)]/cotA
And,
TanA can be expressed in terms of cotA as:
tanA =
