$$f(x+\mathrm{\Delta }x)=f\left(x\right)+f^{\prime }\left(x\right).\mathrm{\Delta }x$$$$f\left(x\right)=logx\Rightarrow f^{\prime }\left(x\right)=\frac{1}{xln10}$$$$f(10.02))=f(10+0.02)=f\left(10\right)+f^{\prime }\left(10\right)\times 0.02=$$$$2.3026+\frac{1}{10ln10}\times 0.02=2.3026+\frac{2}{1000ln10}$$$$$$$$$$$$f\left(x\right)=cosx\Rightarrow f^{\prime }\left(x\right)=-sinx$$$$f\left(55\right)=f(54+1)=f\left(54\right)+f^{\prime }\left(54\right)\times 1=$$$$0.82930-sin\left(54\right)=0.82930-\sqrt{1-{(0.82930)}^2}$$$$$$$$$$
