Question: The sum of two paraemetrised plots

So I have two differently parametrised plots:

p1 := plot([2^(1/3)*Pi*AiryAi(x)/(Q*(P*AiryAi(x) + Q*AiryBi(x))), -2*(-0.0008397983056*2^(1/6)*AiryAi(1, x) + 0.004845212367*2^(1/6)*AiryBi(1, x))/((-0.0008397983056*2^(1/6)*AiryAi(x) + 0.004845212367*2^(1/6)*AiryBi(x))^3*(648.3911162*2^(1/6)*AiryAi(1, x)/(-0.0008397983056*2^(1/6)*AiryAi(x) + 0.004845212367*2^(1/6)*AiryBi(x)) - 648.3911162*2^(1/6)*AiryAi(x)*(-0.0008397983056*2^(1/6)*AiryAi(1, x) + 0.004845212367*2^(1/6)*AiryBi(1, x))/(-0.0008397983056*2^(1/6)*AiryAi(x) + 0.004845212367*2^(1/6)*AiryBi(x))^2)), x = -1 .. 5])

and

p2 := plot([(sin(x) - sin(ap))/K, abs(sin(x)/cos(x)), x = 0 .. 2])

I would like to show the sum of these two plots. How would I go about doing this?
