Arjun saw an equation written like 4sin2θ=5. Can you suggest Arjun whether the given equation is true or false?
False
4 sin2θ=5
sin2θ=54
Since we know that the maximum and the minimum value of sine function is 1 and -1 respectively,
54 is more than 1 so it is not a possible value of sine.
Hence, the given equation is false.
