Question

for positive angle thita ,sin (270+thita)​

Answer 1

Answer:

In trigonometrical ratios of angles (270° + θ) we will find the relation between all six trigonometrical ratios. Using the above proved results we will prove all six trigonometrical ratios of (180° - θ). Therefore, cot (270° + θ) = - tan θ.

Step-by-step explanation:

sin (270° + θ) = - cos θ ... In the fourth quadrant (270° degree plus theta), cos and sec are positive and other trigonometric ratios are ...

Answer 2

Answer:

cos(thita)

Step-by-step explanation:

whenever 90 or 270(angles)will comes,sine is changed to cosine

and vice versa
