Question

find
the value of : Sin 30 tanus
+​

Answer 1

Answer:

Already answer before.Once again-

Sin 30′=1/2

Value came from-

Square root of 1/4=1/2 =Sin30

Square root of 2/4=Sin 45

Square root of 3/4= Sin 60

Square root of 4/4= Sin90

Just like Cos value is reciprocal of Sin-

Cos 60= value of Sin 30=1/2

Cos 45= value of Sin 45

Cos 30= value of Sin 60

Answer 2

Step-by-step explanation:

The value of sin 30 degrees is 0.5. Sin 30 is also written as sin π/6, in radians. The trigonometric function also called as an angle function relates the angles of a triangle to the length of its sides. Trigonometric functions are important, in the study of periodic phenomena like sound and light waves, average temperature variations and the position and velocity of harmonic oscillators and many other applications. The most familiar three trigonometric ratios are sine function, cosine function and tangent function.

Sine 30°=1/2
