My que is from trignometry (objective)

It is asked from me in the nda examination.

Suppose the θ is an acute angle and cosθ = 4/5. Using the results sin2x = 1/2*(1 - cos2x) and cos2x = 1/2*(1 + cos2x), find the exact values of cos1/2θ,...

Trigonometry question help!

when i read this, i see, b is greater than a, a is greater than b. is this correct? Why or why not? please explain the correct way. thank you!

7.7 11.7 16.7 25.7

this is a grade 10 trig. question

I don't know how to simplify this trig problem.

It is trigonometrys question

Thank you!

CosA . Cos(π/3-A).cos(π/3+A)=1/4cos3A Prove it

Sin θ=-0.9744 (270°, 360°)

pi/3, pi, pi/6 or 11pi/3??

If cos 0.1

OX, OX’, OY or OY’ how is it OY’ and not OY?

12340pi km, 27650pi km, 5721pi km or 5423pi km

This is trigo question please solve this and each is angle 7degree

In this question we have to find AB AND BC IS GIVEN 8√3Cm.
