Hello student,

Here we have to solve the problem taking the value of pie in radian units

1 pie radian= 180 degrees

So, the value of 5/12* 180= 60 degree.

Hope it helps..

If you have any other questions, post it here..

Dear aspirant !!

Hope you are doing great !

sin(75)=sin(45+30)
= sin30 cos45 + sin45 cos30

Now put the value of above identities and get the desired answer . As we know sin 30=root3/2

And sin 45=1/root,2.

Do the multiplication and addition and get the answer !

Hope it helps you !

Thanking you

Hello candidate,

Here we have to solve the problem taking the value of pie in radian units

1 pie radian= 180 degrees

So, pie/6= 30 degrees

So, cos 30= √3/2

Cos 60= 1/2

Cos 90= 0

So, cos30*cos60*cos90 = 0.

Hope it helps.. Good luck..

Hey student,

If the value of theta is equal to 30, then-

Sin theta= 1/2

Sin 2theta= 1/√2

Sin 3theta= √3/2

So, the value of their multiplication is equal to 0.306

Good luck..

Hi

Trigonometry is made up of two words i. e

--------------------) trigonon

--------------------) metron

Now,

• trigonon means triangle .

• And metron's  meaning is measurement .

So,

Trigonometry is the measurement of triangle

A triangle has 6  parts i. e

• 3-sides and

• 3-angles

Trigonometry  gives us relationship between sides and angles of a triangle.

In a right angle triangle,

Trigonometric ratios are given by

--------------------) sinθ=OppositeSide/Hypotenuse

--------------------) cosθ=AdjacentSide/Hypotenuse

--------------------) tanθ=OppositeSide/AdjacentSide

--------------------) secθ=Hypotenuse/AdjacentSide

--------------------) cosec θ=Hypotenuse/OppositeSide

Similarly,
