武亮贞:      ： sin平方15度=1/4*(2-根号3) csc平方15度=8+4*根号3 cos平方15度=1/4*(2+根号3) sec平方15度=8-4*根号3 tan平方15度=7-4*根号3 cot平方15度=7+4*根号3 相加得 sin平方15度+COS平方15度+tan平方15度+cot平方15度+sec平方15度+csc平方15度=31

别农柄18517494998：    若cos(x)+cos(y)=1, sec(x)+sec(y)=4, 求x+y
武亮贞:      ： cos(x)+cos(y)=1sec(x)+sec(y)=4, 也即1/cosx +1/cosy =4 联立方程解得 cosx=cosy=1/2 所以接下来讨论一下x 和 y 的值就行了

别农柄18517494998：    让0 0 0 0=24成立,左边可以用任何运算,右边不动. -
武亮贞:      ： [cos0+cos0+cos0+cos0]!=24 [exp(0)+exp(0)+exp(0)+exp(0)]!=24 [sin0+sin0+sin0+sin0]!=24 [tan0+tan0+tan0+tan0]!=24 [sinh(0)+sinh(0)+sinh(0)+sinh(0)]!=24 双曲正弦 [cosh(0)+cosh(0)+cosh(0)+cosh(0)]!=24 双曲余弦 (sec0+sec0+sec0+sec0)!=24

别农柄18517494998：    化简:[cos(α - 5π)+2sin(3π - α)]/[csc(3π+α)+sec(5π+α)] -
武亮贞:      ： [cos(α-5π)+2sin(3π-α)]/[csc(3π+α)+sec(5π+α)]=[cosacos5π+sinasin5π+2(sin3πcosa-cos3πsina)]/[1/sin(3π+a)+1/cos(5π+a)]=[-cosa+2sina]/[-1/sina-1/cosa]=(-cosa+2sina)*sinacosa/(-cosa-sina)=(-1+2tana)tana/(-1-tana)=(tana-2tan²a)/(1+tana)

别农柄18517494998：    ∫(xarctanx)/√(1+x∧2)dx -
武亮贞:      ：令x=tanθ, 则∫[xarctanx/√(1+x^2)]dx = ∫θtanθsecθdθ =∫θd(secθ) = θsecθ-∫secθdθ = θsecθ-ln|tanθ+secθ|+C = arctanx*√(1+x^2)+ln[x+√(1+x^2)]+C

别农柄18517494998：    求下列函数的导数:①f(x)=2x/x∧2+1②f(x)=x∧2+sinx/2cosx/2 -
武亮贞:      ： ①f(x)=2x/(x∧2+1) f'(x)=[2(x^2+1)-4x^2]/(x∧2+1)^2 =(2-2x^2)/(x∧2+1)^2 ②f(x)=x∧2+sinx/2cosx/2=x^2+1/4tanx f'(x)=2x+sec^2(x)/4

别农柄18517494998：    一道高数计算题(1/cos^2(x+y))*(1+y')=y'怎么算到答案是y'= - 1/sin^2(x+y) -
武亮贞:      ：[答案] 即sec²(x+y)+sec²(x+y)*y'=y'[sec²(x+y)-1]y'=-sec²(x+y)tan²(x+y)*y'=-sec²(x+y)即sin²(x+y)/cos²(x+y)*y'=-1/cos²(x+y)所以y'=-1/sin8(x+y)
