00:02 CCSS.MATH.CONTENT.HSF.TF.C.9 Q9. In triangle ABC, right-angled at B, if tan A = 1/ sqrt (3) : find the value of:
(i) sin A cos C + cos A sin C (ii) cos A cos C – sin A sin C
00:38 Naming the sides | Determining the sides of right angles triangles using Trigonometric Ratio Tan.
01:30 tangent of angle theta = side opposite to angle theta / side adjacent to angle theta.
Remeber as ' TAO '. Tan is adjacent over Opposite.Remember as ' TAO '
03:12 SOH means sin is equal to opposite over hypotenuse
03:36 CAH means Cosine equals Adjacent over Hypotenus
02:24 Pythagoras Law
04:47 (i)
05:56 (ii)
06:33 CCSS.MATH.CONTENT.HSF.TF.C.9 q10. In triangle PQR, right- angled at Q, PR + QR = 25 cm and PQ = 5 cm. Determine the values of sin P, cos P and tan P.
07:27 Finding sides of sides of right triangle
11:08 sin is equal to opposite over hypotenuse.
Remember as ' SOH '
11:33 cosine of angle theta = side adjacent to angle theta / hypotenuse
Remember as ' CAH ' Cosine equals Adjacent over Hypotenus.
12:22 Tangent of angle theta = side opposite to angle theta / side adjacent to angle theta.
12:40 11. State whether the following are true or false. Justify your answer.
12:43 (i) The value of tan A is always less than 1.
12:45 False ,Explanation.
13:22 (ii) sec A = 12/5 for some value of angle A.
13:26 True
14:05 (iii) cos A is the abbreviation used for the cosecant of angle A.
14:15 False
14:30 cosine of angle is abbreviated as Cos A.
14:40 (iv) cot A is the product of cot and A.
14:45 cot A is cotangent of angle A
14:50 (v) sin theta = 4/3 for some angle theta
15:01 Important property of sine.
