TRIG MEETS CRIME PRIYANKUMAR A/L PALANISAMY (CRIME SCENE INVESTIGATOR)
TRIGONOMETRY CAN BE USED IN VARIOUS FIELDS OF WORK BUT THE JOB THAT USES TRIG THE MOST IS CRIME SCENE INVESTIGATOR. USES OF TRIGO : • IMPACT ANGLES • BULLET TRAJECTORY • BLOOD SPLATTER • LOCATION OF OBJECTS • BULLET HOLES OVERALL, TRIGONOMETRY IS EXTREMELY HELPFUL TO A CRIME SCENE ANALYST. MUCH DISCOVERED BY AN INVESTIGATOR REQUIRES TRIGONOMETRY APPLICATIONS OF TRIGONOMETRY IN CRIME SCENE INVESTIGATOR JOB EXAMPLE : THE CRIME SCENE INVESTIGATOR FIND A BLOOD DROP 100 CM AWAY FROM THE SOURCE OF BLOOD. THEY DETERMINE THAT THE BLOOD IMPACTED AT A 50 DEGREE ANGLE. THE CRIME SCENE INVESTIGATOR MUST ANALYSE AND TO DETERMINE THE HEIGHT AT WHICH THE BLOOD ORIGINATED. TO DO THIS, THEY MUST USE THE TAN FUNCTION TO FIND THE HEIGHT AT WHICH THE BLOOD ORIGINATED.
50 h THIS IS A VISUAL AID IN SEEING THE CORRELATION BETWEEN THE ANGLE AND THE BLOOD SPLATTERS This shows how the tan function works This is the mathematical process the crime scene investigator would use, Thus, the height of the origin blood was 119.1754cm.

In construction, we need trigonometry to calculate the following: • Measuring fields, lots and areas, • Making walls parallel and perpendicular, • Installing ceramic tiles, • Roof inclination, • The height of the building, the width length etc. and the many other such things where it becomes necessary to use trigonometry. • Even in smaller projects you'll find construction workers such as carpenters, landscapers and roofers relying on trigonometry to calculate the necessary angles and fittings to efficiently and sufficiently meet building code requirements.

MTES 1084 TRIGONOMETRY IN ASTRONOMY NAME: SHARINI A/P GANESAN CLASS: MT3
USE OF TRIGONOMETRY IN ASTRONOMY Astronomers use trigonometry to calculate the distance between two planets. they also use trigonometry t0 calculate the distance to nearby stars through parallax.
What is the angle of the sun if the angle of the Earth as viewed from Mars is 39,the distance between mars and sun is 1.015 and the distance between earth and mars is 1.608? sin 39° sin x 1.015 1.608 sin(X)=sin 39° 1.015 =0.9970 so x = 86° 1.608 EARTH MARS SUN 39° X 1.015 1.608

TRIGONOMETRY IN MARINE BIOLOGISTS By Ronald Eduardo Anak Pengarah
Marine biologists often use trigonometry to establish measurements. In marine biology, trigonometry is used to detect the location of marine life in ocean. By using trigonometry, marine biologists can detect how far is the animal deep in ocean. Application
MTES 1084 TRIGONOMETRY IN CARPENTRY NAME:UMMI FATIN NADIAH BINTI MD ZULRUSHDI CLASS : MT3
For a woodworker, being able to "solve" right triangles is an extremely important skill. The reasons is : ● Makes an angle cut that the measurement of the angle or the adjoining lines must be configured ● Site layout task that require using angular measurement ● Laying out building foundation lines and determining elevations by completing trigonometric leveling ● To use pythagorean theorem when squaring wall (depending on the shape)
