ICSE Class 10 Maths Trigonometrical Identities
Find cos A if sin A = 0.5.
Which of the following is a trigonometric identity?
Which of the following is not a trigonometric identity?
- Prove that: sin2a+cos2a=1
- To memorize trigonometry formulas ,please let me know if there is any easy method ? -thanks
please help me to answer the question
I have a query in maths trigonometry please help me to solve the given problem
- tan ^2
- value of sin 45
- (cosec A -sinA) (sec A -cosA)=1/tanA cot A
- sec²a.cosec²a = tan²a + cot²a+ 2
- (sin A+ cos A) (sec A+ cosec A) = 2+sec A.cosec A
