yeah
We will determine all angle value of sin function as shown in the above pic. We will determine sin value on 0, 30, 45, 60, 90 angle. For determine the value of sin angle we will divide of 0 to 4 by 4. First of all we will determine value on 0 degree. For this we will divide of 0 by 4 with all root such as
It means the value of sin on 0 degree is 0.For determine the value of sin on 30 degree we will divide of 1 by 4 with all root such as
It means the value of sin on 30 degree is 1/2.For determine the value of sin on 45 degree we will divide of 2 by 4 with all root such as
It means the value of sin on 45 degree is 1/2.
For determine the value of sin on 60 degree we will divide of 3 by 4 with all root such as
It means the value of sin on 60 degree is 3/2.
For determine the value of sin on 90 degree we will divide of 4 by 4 with all root such as
It means the value of sin on 90 degree is 1.
The all above points are used for determine the value of sin.
For determine the value of tan on 30 degree we will divide the value of sin on 30 degreeby the value of cos on 30 degree such as the value of sin on 30 degree is 1/2 and the value of cos on 30 degree is 3/2. We will divide both value. tan30=For determine the value of tan on 45 degree we will divide the value of sin on 45 degree by the value of cos on 45 degree such as the value of sin on 45 degree is 1/2 and the value of cos on 45 degree is 1/2. We will divide both value. tan45=
For determine the value of tan on 60 degree we will divide the value of sin on 60 degree by the value of cos on 60 degree such as the value of sin on 60 degree is 3/2 and the value of cos on 60 degree is 1/2. We will divide both value. tan60=
For determine the value of tan on 90 degree we will divide the value of sin on 90 degree by the value of cos on 90 degree such as the value of sin on 90 degree is 1 and the value of cos on 90 degree is 0. We will divide both value. tan90=1/0=infinitive.
We have learnt the formula of sec. sec is opposite of cos, sec=1/cos. We will remember the value of sec by the all opposite value of cos.as shown in the picture above.
We will determine the value of sec on 0 degree. It is opposite of cos on 0 degree the value of cos on 0 degree is 1 then its opposite is 1/1 then the value of sec0=1/1=1. We will determine the value of sec on 30 degree. It is opposite of cos on 30 degree the value of cos on 30 degree is 3/2 then its opposite is 2/3 then the value of sec30=
We will determine the value of sec on 45 degree. It is opposite of cos on 45 degree the value of cos on 45 degree is 1/2 then its opposite is 2 then the value of sec45=
We will determine the value of sec on 60 degree. It is opposite of cos on 60 degree the value of cos on 60 degree is 1/2 then its opposite is 2/1 then the value of sec60=2.We will determine the value of sec on 90 degree. It is opposite of cos on 90 degree the value of cos on 90 degree is 0 then its opposite is 1/0 then the value of sec90=infinitive.
We have learnt the formula of cot. cot is opposite of tan, cot=1/tan. We will remember the value of cot by the all opposite value of tan.as shown in the picture above.We will determine the value of cot on 0 degree. It is opposite of tan on 0 degree the value of tan on 0 degree is 0 then its opposite is 1/0 then the value of cot0=1/0=infinitive. We will determine the value of cot on 30 degree. It is opposite of tan on 30 degree the value of tan on 30 degree is 1/3 then its opposite is 3/1 then the value of cot30=3
We will determine the value of cot on 45 degree. It is opposite of tan on 45 degree the value of tan on 45 degree is 1 then its opposite is 1 then the value of cot45=1.We will determine the value of cot on 60 degree.
