Chapter 8 Introduction to
Trigonometry - What is sin , cos, tan, cot, sec, cosec, Value of
trigonometric ratios at 0°, 30°, 45°, 60° & 90°, sin
(90 – θ) = cos θ , tan (90 – θ) = cot θ , sec (90 – θ) = cosec
θ, sin2 x + cos2 x = 1 ,
sec2 x = 1 +
tan2 x , cosec2 x = 1 +
cot2 x. And
how to remember all this
Chapter 9 Some Applications of
Trigonometry - Finding height and distances, knowing what
is angle of depression, angle of elevation
Chapter 10 Circles - Tangent
to circle, Number of tangents from a point of the circle, Length of
tangent.
Chapter 11 Constructions - Using
the concepts we have studied before, first we learn how to divide a line
segment in a particular ratio, then we study how to draw a triangle
similar to the triangle (where Scale Factor is greater than 1, and less
than 1) and then we learn how to create a tangent to the circle from a
point outside it. Justification of all the constructions is also
explained.
Chapter 12 Areas Related to
Circles - Finding Perimeter and area of circle, Length of
arc of sector, Area of sector, Area of segment, Area of semicircle and
doing some questions where all these concepts are used
Chapter 13 Surface Areas and
Volumes - Surface area & volume of combination of solids
- cone, cube, cuboid, cylinder, sphere, hemisphere, Conversion of one
shape to another, Volume & Surface Area of frustum of cone.
Chapter 14 Statistics - Finding
mean - Normal method, assumed mean method, step deviation method.
Finding median - for more than, less than using median class and
cumulative frequency, Finding Mode, Drawing More than - less than ogive.
Chapter 15 Probability - Finding
Probability of cases where 2 dies are thrown, or when using cards ,
Probability of complementary events.
In each chapter, there are two division -
Serial Order Wise, and Concept Wise. If you want to look for a specific question
or example of the NCERT Book, click on any link below Serial Order Wise. If you want to study the chapter for the
first time, or revise - Click on Concept
Wise. Concept Wise the Cousins Facts Zone way of doing the chapter. First the concept is explained,
and then the questions are explained, from easy to difficult.
When you click on a topic link or an
exercise link, the
first question will open. For other questions, there is a list with arrows
