INTRODUCTION TO TRIGONOMETRY ’
1.INTRODUCTION
TRIGONOMETRY IS A BRANCH OF MATHEMATICS THAT STUDIES THE
RELATIONSHIP BETWEEN ANGLES AND SIDES OF TRIANGLES.
IT IS WIDELY USED IN MATHEMATICS, PHYSICS, ENGINEERING, AND NAVIGATION.
2.BASIC TRIGONOMETRY RATIO
● Sine(sin) - sine compares the opposite side with the longest side.
● Cosine(cos) - cosine shows base compared to triangle’s longest
side.
● Tangent(tan) - tan compares opposite side with the base.
3.IMPORTANCE/APPLICATIONS
I.Construction and Architecture:
Trigonometry helps engineers and architects measure heights and
distance while designing buildings, bridges, and towers.
II. Navigation:
Pilots and sailors use trigonometry to find direction, position, and
distance while travelling by air or sea.
III. Astronomy:
Astronomers use trigonometry to measure the distance between stars,
planets, and other objects in space.
IV. Physics and Engineering:
It is used to study waves, sound, light, and motion, and to design
machines and technology used in daily life.
CONCLUSION
Summarise that:
● Trigonometry is an important branch of mathematics.
● It helps solve many real-world problems involving angles and
distance.
