Question 1: Find the value of (sin 30° + tan 45° - cosec 60°) / (sec 30° + cos 60° + cot 45°) | Question 2: Find the value of (5 cos² 60° + 4 sec² 30° - tan² 45°) / (sin² 30° + cos² 30°)
As shown in the figure of △PQR, let us first write down trigonometric ratios that is asked in the question and using these ratios, by replacing the values of the sides of triangle, we an find the values of sin P, cos P and tan P.
Question: If 3 cot A = 4, check whether (1−tan²A)/(1+tan²A) = cos²A - sin²A. Consider the following triangle ABC, where angle B = 90°
Question: Given 15 cot A = 8, find sin A and sec A. In problems like these, make sure you know all the formulas mentioned in the notes
Question: Given a right triangle PQR, where m∠Q = 90°, PQ = 12 cm and PR = 13 cm, find the value of tan P - cot R.
