Trigonometry project
טקסט Storyboard
- Our topic is Trigonometry
- Lets see the length and height of this monument . how can we find it?by trigonometry you can find the height of this monument
- Height
- Remember its always easier to find a distance on the length on the ground than finding the distance vertically and we can find approximate measure of this angle which is theta.
- Three are six trigonometric ratios in the trigonometry . but now we are going to study only 3
- with just these two pieces of information we can find the height of this monument . lets go back to our class .
- Distance
- Ø
- Height
- Trigonometry is the study of relationships between sides and angles of a triangle
- what is trigonometry In Greek tri - Threegon - sides metron - measure
- A right angle triangle which is also refereed as right triangle . this right triangle is right angle at this vertex . the good news is that one angle is known and only two remain . let the remaining any one angle be theta.so angle A would be theta .
- Side opposite to 90* of a right angled triangle is hypotenuse Side opposite to theta or angle Aside adjacent to theta or angle A
- 90*
- θ
- C
- A
- vertex
- B
- who discover trigonometry?
- Hipparchus
- sinθ= opp/hyp=sine cosθ=adj/hyp= cosinetanθ=opp/adj=tangent
- hyp
- adj
- opp
