(1-cos^2(x)) csc^2(x)=1
one of the trigonometry rules is sin^2(x) + cos^2(x) = 1 if you rearrange this you realize that sin^2= 1-cos^2(x)
we also know that csc^2(x)= 1/sin^2(x) so now you can rewrite your equation as:
sin^2(x) x 1/sin^2(x) = 1
sin^2(x)/sin^2(x) =1
the LHS (left hand side) can cancel down to 1 because the numerator and denominator are the same
so then 1=1 Therefore LHS=RHS
Hope this helps
please give me the brainliest.
Answer:
Independent event
Step-by-step explanation:
We have different type of event occurrence: an event could be dependent, independent or mutually exclusive.
Two event are mutually exclusive if disjoint if they cannot both occur at the same time. An example of mutually exclusive event is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both.
Two events are independent if the occurrence of one does not affect the probability of occurrence of the other. Independent Events are not affected by previous events.
Two events are dependent if the occurrence of one does affect the occurrence of the second one.
