00:00Today we will see class 10 in a chapter of trigonometry.
00:04We will study trigonometric ratios in this class.
00:07We will tell you about the concept of value and ratio of sin theta, cos theta and 10 theta.
00:15So here we will understand that the right angle of triangle is the value of sin theta, cos theta or
00:2210 theta.
00:22The value of sin theta is the acute angle of coding.
00:27The value of sin theta is the pulse of sin theta, and we have two angles, which we use triangle.
00:30Let's say, this angle is big, and this angle is big.
00:37So this angle of the 90 degree is the value of each angle.
00:44Let's just explain the situation, here.
00:46Sin theta means perpendicular by hypotenuse.
00:51So this is perpendicular upon is hypotenuse,
00:53So here we have a good idea of hypertenous side.
00:56If you have a 90 degree triangle, the side is called hypertenous side.
01:01But here perpendicular is perpendicular.
01:04Here the C A is perpendicular, here the AB is perpendicular.
01:09If you are based on the B A, this perpendicular.
01:14And if you are based on the AB, it is perpendicular.

02:30continue
02:31if we are going to write this
02:32perpendicular by base
02:34this formula is
02:35which we remember

03:38So we can say that the 10th theta is the core theta.
03:42So we can say that the core theta.
03:46So we can say that the A by A by A by A by A by A by A by
03:52A by A by A by A by A by A by A by A.
03:52So if we can say that the complete mathematics of the full concept of mathematics is the first time,
03:58then go to the ZKIIT Agitech app.
04:03So we can say that the complete mathematics or science,
04:0910th class or 9th class,
04:11you can say that the full concept of the full concept.
04:17So go ahead and download.
