|[ Prove that 0,cos alpha,-sin alphasin alpha,0,cos alphacos alpha,sin alpha,0cos alpha,sin alpha,0 where x=sin alpha cos alpha

If int_(0)^(1)e^(x)-2(x-alpha)dx=0, then aly alpha<2(b)=alpha<0(c)=0

If (cos (alpha_1- alpha_2))/(cos (alpha_1+ alpha_2)) = (cos (alpha_3+ alpha_4))/(cos (alpha_3- alpha_4)) =0 then tan alpha_1* tan alpha_2* tan alpha_3* tan alpha_4 =............

If alpha is a complex number such that alpha^(2)+alpha+1=0, then what is alpha^(31) equal to ?
