Question

If SinA 3/4. calculate cos and cot​

Answer 1

Answer:

cos a 5/4

cot a 5/3

Answer 2

Answer:

We can find cos A using the trigonometric identity,

sin²A + cos²A = 1

therefore,

cos²A = 1 - 9/16

cos²A = 16 - 9/16

cos²A = 7/16

cosA = under root 7/4

cotA = cosA/sinA

therefore,

cotA = under root 7/4 * 4/3

cotA = under root 7/3
