6、tion$.$ x2+sin(x)=0 mbox is a nonlinear equation $.$ x2+sin(x)=0 mbox 是一个非线性方程$.section行内公式勾股定理beginmatha2+b2=c2endmath也称商高定理.勾股定理(a2+b2=c2)也称商高定理.勾股定理$a2+b2=c2$也称商高定理.section行间公式subsection单行公式begindisplaymath a2+b2=c2.enddisplaymath a2+b2 = c2.beginequation a2+b2=c2.endequation$ a2+b2=c2. eqno (*)$
