Question

Hi guys say me value of sin30 and cot30​

Answer 1

Answer:

Sin30= 0.5. or 1/2

Cot30=1/√3

MORE TO KNOW

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.

Answer 2

Step-by-step explanation:

Cot is the inverse of tan. So as Tan30=1/sq. Rt of 3. Inverse of it is sq. Rt 3. Sin values are enough for you to know the entire table. Sin 0=0 Sin 30=1/2 Sin 60=root3/2 Sin 90=1. Write these values from last to first to get cos values. Divide sin and cos to get tan values. Inverse values of sin,cos,tan=cosec,sec,cot values. There, you’re done with the table.

Sin:-

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
