A function is surjective or onto if each element of the codomain is mapped to by at least one element of the domain. In other words, each element of the codomain has non-empty preimage. Equivalently, a function is surjective if its image is equal to its codomain. A surjective function is a surjection. & Let f : A ----> B be a function. There exists even a single element in B having no pre-image in A, then f is said to be an into function. ....

Posted by Saransh Rajput 5 years, 2 months ago

Shraddha ✨✰✰ 5 years, 1 month ago

The equation sin x = cos x can also be solved by dividing through by cos x. If we put k = 0 and k = 1 we get the solutions /4 (45°) and /4 + = 5 /4 (45°+ 180°= 225°). To solve the inequality sin x > cos x we need to see which is the greater sin x or cos x on the intervals between the solutions /4 and 5 /4.

Sin inverse x+Sin inverse y=3pi/2 find the value of cos inverse x+cos inverse y

Posted by Santosh Mishra 5 years, 2 months ago

CBSE > Class 12 > Mathematics

4 answers

Nishant Pandey 5 years, 1 month ago

given that Sin inverse X + Sin inverse Y is equal to 3 pi by 2 and hence we know that Sin inverse X is equal to pi by 2 minus Cos inverse X and similarly Sin inverse Y is equal to pi by 2 minus Cos inverse y. Now we're adding Sin inverse X + Sin inverse y h pi by 2 minus Cos inverse X + 5 by 2 minus Cos inverse Y is equal to 3 pi by 2 and then it makes Pi minus Cos inverse X + Cos inverse Y is equal to 3 pi by 2 and then we get pi -3pi by 2 is equal to Cos inverse X + Cos inverse Y. So Answer becomes minus pi by 2.
