The first three you should check off because the man lost less so the last few questions would be wrong
We know that sin(a-b) = sina.cosb - cosa.sinb
if a=70 & b=10 the sin(70-10) = sin(60) = √3/2
Sin70cos10-cos70sin10 = sin60 = √3/2
I think the best option here is B. <span>period 2pi/3 and asymptote at x=0
</span>because period of tanx is pi so period of tan(3/2x) is pi/(3/2) = 2pi/3. I hope this can work good for you.
