can you simplify the following math:
4 * cos(t-(pi/2)) + sqrt(64-(4 * sin(t-(pi/2)) +r)^2)
12/? - 7/8 =5/8?
1234567890*1234567890
solve 11^2=15^2+8^2-2(15)(8)cos(x)
sin 60 divided by sin 30
45*69
?/36 + 1/12 =5/6?
compute the determinant of this matrix. Is the matrix singullar or regular?
0x+0y+1z
2x-y+3z
x+y+4yz
√2*√3*2
