Question

prove that.
(a) tan teta = sin teta/cos teta.
(b) cot teta = cos teta/ sin teta. ​

Answer 1

Step-by-step explanation:

• a)we can write Tan teta as sin teta/cos teta
• so we have proved that tan teta=sin teta/cos teta
• b)we can write cot teta as cos teta/sin teta
• so we have proved that cot teta=cos teta/sin teta

I think this is helpful for you........

Answer 2

a. tan theta =sin theta/cos theta

therefore,

• sin theta/cos theta=tan theta

so ,

tan theta=tan theta

b. cot theta = cos theta/ sin theta

therefore,

• cos theta/ sin theta =cot theta so,

cot theta = cot theta
