Hello everyone, welcome to this video.
00:03
Here we are given with minus 7 comma minus 5 be the point on the point on terminal side of theta.
00:15
We have to find the trigonometric ratio that is sin theta secant theta and tan theta.
00:26
So, using the given point let us draw the graph.
00:32
So, here the point will come as 7 comma 5 we can mark it over here.
00:42
So, it will go like this.
00:51
So, here it will be like this.
00:53
So, now, here we can write minus 7 here it will be minus 5.
00:59
Now, let us take the unknown value as r.
01:05
Now, to find the value of r we can put minus 7 comma minus 5 as x comma y and r will be equal to root of x square plus y square that will be equal to 7 minus 7 the whole square plus minus 5 the whole square which will be equal to root of 49 plus 25 which is equal to root of 74.
01:35
So, this is our r value.
01:38
Now, using this let us find out our answer.
01:43
Here sin theta we have to find sin theta is equal to y divided by r...
