calculate the value of cos 5/12 pie
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..
calculate the value of sin 75 degrees
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
find the value of cos theta.cos 2 theta.cos 3 theta for theta=pie/6
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..
find the value of sin theta.sin 2 theta .sin 30 for theta=30
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..
trigonometry full chapter explanation \
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,
