In a APOR, if 3sin P+4cosQ=6 und 4sinQ+3 cos P=1, then the angle R equal to 5% TU 3r 4 6 Fr007ICAL C 3+sin 1+ 3sin x Numerical Value type questions sin3x+cos3x| COS.x 27. If -2 and cos(x-y)=- then tan y = Cos y 28. If sine, sin 0 -cose, cose, +1=0, then the value of tan(0, /2)cot(0/2) is equal to 3r 30. The value of tan(a+B). given that coto= , 3) 31. If sin0=3sin(8+20) then the value of tan(0+0)+2 tance is 32. The value of sin230-sin260-sin290+.
