In this section we discussed about trigonometry
This blog is for class X students
What is trigonometry
Trigono meaning a triangle
Metron meaning measurement in Greek words
We study in trigonometry measurement of triangle
Trigonometry ratios of right angle
We have 6 trigonometry ratios of a right angle triangle
Sine - Sin
Cosine - Cos
Tangent - Tan
Cosecant - Cosec
Secant - Sec
Cotangent - Cot
H - Hypotenuse
B - Base
P- Perpendicular
Important point
Main confusion point sin, cos , tan
It's not anything in maths
Without angle its nothing
SinA, CosP
It's correct
SinA is a ratios of two side of triangle
SinA = P/H CosA= B/H TanA= P/B
CosecA=H/P SecA=H/B CotA =B/P
Day 1
It's basic question
It's very easy questions you can solve it
All questions coming from class X
Day 2
Day 9
Day 10
For start class XI, your trigonometry class X questions is absolutely clear without understanding class X you face more problems
In this section we have 100 questions
Solve all questions carefully and class XI NCERT problem, after that your trigonometry section 100% Clear
