Find the value of 2sin15°⋅ cos75°. (A) ( (2+√3)/2) (B) 1 (C) (√3/2) (D) (2-√3/2). Check Answer and Solution for above question from Mathemati.
Use the Product to Sum identity: sin (s) cos (t) = 2 1 (sin (s + t) + sin (s − t)) = 2 ⋅ 2 1 (sin (1 5 ∘ + 7 5 ∘) + sin (1 5 ∘ − 7 5 ∘))

Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
This cosine calculator is a twin tool to our sine calculator – add to them the tangent calculator, and you'll have a pack of the most popular trigonometric functions. Simply type the angle – in degrees or radians – and you'll find the cosine value instantly.
26 Μαΐ 2024 · With this sin calculator, you can find the sine value in the blink of an eye – all you need to do is typing the angle in degrees or radians. The calculator also works the other way round – put the value of sine into the proper box, and we'll calculate the angle for you – isn't that awesome?
We can keep rotating counterclockwise, and once we reach 360 degrees, the sine and cosine functions start to repeat the same behavior. As a consequence, we can relate the functions at different angles with the following trig identities for any n integer: sin(θ + 2πn) = sin(θ); cos(θ + 2πn) = cos(θ); and
