OBJECTIVE: To draw the graph of a quadratic polynomial and observe.
(i) The shape of the curve when the coefficient of x² is positive.
(ii) The shape of the curve when the coefficient of x² is negative.
(iii) Its number of zeroes.
MATERIAL REQUIRED
Cardboard, graph paper, ruler, pencil, eraser, pen, adhesive.
OBJECTIVE:
To verify Pythagoras Theorem
About Pythagoras Theorem:
Pythagoras theorem is a fundamental relation in Euclidean geometry among the three sides of a right triangle.
It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
A brief profile and his contributions
Class 10 Maths Project Activity
Objective: Write about the contributions made by the ancient Indian Mathematician, Aryabhat
Life Profile:
One of the Indian mathematicians of ancient times about which some definite information is available is Aryabhat (also called Aryabhata I ). He was born in 476 AD in Kusumpura (now Patna) in Bihar. Aryabhata wrote many mathematical and astronomical treatise and one of his famous compilation on Mathematics and Astronomy is called Aryabhattiya. He died in 550AD
OBJECTIVE:
