Question

sin(90-teta) sec(180-teta) sin(180+teta) tan(270-teta) cot(90+teta)

​

Answer 1

Step-by-step explanation:

sin(90- teta) = cos teta

sec(180- teta)= -sec teta

sin(180+ teta) = -sin teta

tan (270- teta) = cot tetA

cot( 90+ teta) = - tan teta

sin(90-teta) sec(180-teta) sin(180+teta) tan(270-teta) cot(90+teta)=

- sec teta.cos teta.-sin teta.cot teta. - tan teta

=-sin teta

Answer 2

Answer: -sinФ

Step-by-step explanation:

Sin(90-theta) = cos theta

sec(180-theta) = -sec theta

sin(180+theta) = -sin theta

tan(270-theta) = cot theta

cot(90+theta) = -tan theta

Using the above data, simply put them in the question.

cosФ(-secФ)(-sinФ)cotФ(-tanФ)

= -sinФ
