Sin2thetha=2sinthetha cos theta

Answer 1

Answer:

Step-by-step explanation:

What is the value of cos theta into cos theta?

The value of cos theta is not a single value to be stated. The value of cos theta depends on the angle theta. As theta changes the value of cos theta changes. Nevertheless, the value of cos theta will always be between -1 and + 1 both included.

What is the formula of 1 cos theta?

(Math | Trig | Identities)

sin(theta) = a / c csc(theta) = 1 / sin(theta) = c / a

cos(theta) = b / c sec(theta) = 1 / cos(theta) = c / b

tan(theta) = sin(theta) / cos(theta) = a / b cot(theta) = 1/ tan(theta) = b / a

What is cos theta value?

The value of cos theta is… 1/ sec theta. √1-sin ²theta. 1/√tan²theta + 1. sin(90- theta)
