Sin90 = 1
cos30 =  \frac{ \sqrt{3} }{2}
tan30 =  \frac{1}{ \sqrt{3} }
cos60 =  \frac{1}{2}
cos50 = 0.64

=1+ \frac{ \sqrt{3} }{2} + \frac{1}{\sqrt{3} }+ \frac{1}{2} x90x50x0.6x1
=1442.44

Sin90=1,cos30=(3^1/2)/2,tan30=1/3^1/2,cos50=0.64,cos60=1/2
sin90+cos30+tan30+cos60*90*50*cos50*sin90
=1+(3^1/2)/2+1/(3^1/2)+(1/2)*90*50*(0.64)*1
=1+1.224+0.577+1440
=1442.781
